Key words: X-rays, Imaging, Detector, Scintillator, transient phenomena, experimental physics.

Profile and skills required: Ph.D in experimental physics. Knowledge of instrumentation, time-resolved studies, optics, use of simulation tools and "programming for physicists". Knowledge of X-ray imaging and Monte-Carlo methods (geant4) would be a plus.

Presentation of the post-doctoral project, context and objectives:
This post-doctorate aims to develop a measurement chain dedicated to the observation and characterization of fast transient phenomena using X-ray phase-contrast Imaging (XPCI). The challenge is to provide a measurement system that can be deployed in the laboratory on a wide range of experiments that cannot be moved to the synchrotron. The performance targets are justified by issues raised by ONERA and CEA in connection with additive manufacturing, shock wave propagation in low-density polymers, and the diagnosis of carbon composite materials impacted by an electric arc.

For objects with low absorption, such as low-density polymers, liquids or plasmas, conventional X-ray imaging, which provides contrast due to variations in absorption cross-sections, proves insufficient. To complement absorption, it is possible to exploit the phase of X-rays, which enables better detection of inhomogeneities and interfaces between materials. The method chosen here to measure phase is the multilateral shearing interferometry (MLSI). It uses a unique two-dimensional checkerboard phase grating that generates a reference interference pattern on the detector. Introducing an object between the grating and the detector modifies the interference pattern, which is then analyzed by Fourier transform to reconstruct the phase. Requiring only a single phase grating, and presenting minimal X-ray flux loss, this method has favorable intrinsic characteristics in terms of sensitivity, robustness, ease of alignment and versatility, for application to dynamic imaging.

The candidate will first try to dimension the imaging system. He/she will have to set up a static methodology to prepare and optimize imaging under dynamic conditions, with the aim of achieving an imaging rate of > 1 kHz, an exposure time of the order of µs and a spatial resolution range of between 30 and 300 µm. He/she will seek to find the best method for detecting X-ray radiation at the desired rates: indirect detection using a scintillator that converts X-ray photons into visible photons, followed by detection using a high-speed camera, or direct detection using a matrix of pixelated semiconductors hybridized to an electronic chain. To achieve these objectives, he/she will use the CEA imaging bench and simulation codes developed at the CEA (CIVA software). He/she will then demonstrate the dynamic imaging of fast transient phenomena on technologically advanced X-ray sources (secondary laser emission source and liquid anode X-ray tube). Secondly, he/she will study the feasibility of extending the imaging system to very high frame rates (>100 kHz) and/or single-shot "nanosecond flashes".

Magnetic imaging with magnetoresistive sensors on microstructured thin films


Description of the offer:
Postdoc position in spintronics and magnetic sensing
-at the Service de Physique de l’Etat Condensé (SPEC), CEA Saclay, Gif-sur-Yvette, France
-in collaboration with the LICP, CEA-DAM Le Ripault, 37260 Monts, France

Starting date: January 2025.
Duration: 12+12 months
Research area: dynamic magnetic properties, magnetic sensors, magnetic imaging.

The overall strategy of the Oxide and nanomagnetism laboratory (LNO) at SPEC is in-depth understanding of magnetism in condensed matter with a good balance between state-of-the-art research, development of new instruments, and applications. This equilibrium is possible in this field where applications and research are very close. The LNO has specific skills, tools and expertise on the characterization and the development of magnetoresistive sensors with very high sensitivity and for various applications as magnetophysiology, MRI (Magnetic Resonance Imaging), nanometrology, NDT (Non Destructive Testing), automotive...
The postdoc will work in the frame of the CEA internal project called IMAGE (Magnetic imaging on microstructured thin films). Mapping the dynamic magnetic properties (e.g. microwave permeability) of magnetic samples is important for optimizing these materials for applications. The IMAGE project involves developing a setup for mapping dynamic magnetic properties by combining a scanner and giant magnetoresistance magnetic sensors, whose interest lies in their wide frequency detection bandwidth from DC to GHz, adapted to the problem. An initial DC measurement setup has been developed at SPEC. This setup will be adapted to frequency measurements, first in the radiofrequency range, then in the microwave range. 2D microstructured samples will be fabricated by LICP and be characterized by electromagnetic techniques at a global scale. The ultimate aim is to produce magnetic microwave permeability maps (local response) using the setup developed for the samples fabricated by LICP. These never-before-obtained maps will be used to develop and validate models of magnetic materials being developed by LICP for various electromagnetic applications (component noise reduction, antenna performance enhancement, etc.) and design new materials with enhanced performance.
The postdoc will work on the development of the RF setup in order to perform proof of concept permeability maps on calibrated samples. The postdoc will also participate to the development of GMR and TMR sensors and on model to understand and to analyse the maps measured.

Requirements
A successful applicant is expected to have a PhD degree in Physics. He/she must have a solid experimental background in magnetism and RF technics, skills such as instrumentation, setup development and spintronics being particularly relevant.

Contact and Application
The application should include a statement of research interest, CV, a copy of the PhD thesis, or equivalent, published articles and other relevant materials, if available. Also, letter(s) of recommendation can be included.

Objectives
1- Optimization of holographic set-up
Compaction of the holographic bench will be undertaken with new, more powerful laser sources integrated into the bench, whose architecture will be reviewed. An innovative hologram processing method will be developed to overcome the difficulties associated with the high reflectivity of certain areas of the melt. The performance of the algorithm in terms of spatial resolution and topographic
measurement sensitivity will be analyzed.
2- Tests and validations with materials AlSi7 and IN718
In close synergy with the PIMM laboratory (ENSAM Paris), tests will be carried out on AlSi7 and IN718 materials. Estimation of the reflectivity mapping of melting zones will be developed. Based on the analysis of holographic measurement sequences, their correlation with thermal radiation measurements and the analysis of defects observed post-fabrication, characteristic figures will be extracted with a view to creating a defect library.
3- Algorithm for default detection in the melt pool
A defect library will be built up by analyzing laser fabrications with different parameters to identify defects and determine associated singularities in holographic measurements. The development of an AI algorithm based on unsupervised deep learning will be carried out, which should make it possible to detect future structural damage, without the need for labeling work on voluminous training data. This
part will be carried out in close collaboration with the PIMM and MATEIS laboratories (INSA Lyon).

Candidate profile
This thesis is aimed at a motivated and inquisitive graduated (master degree) with higher education, with a good knowledge of (general) photonics and/or instrumentation, and a solid background in signal and image processing. The candidate will need to demonstrate autonomy and creativity to successfully complete the job.

Contract conditions
The PhD student will be based at LAUM, Le Mans, France, but will work very closely with ONERA (Chatillon, close to Paris). Missions to PIMM (Paris) and MATEIS (Lyon) will be planned during the program.

Recruitment from December 2024, funding from the French National Agency for Research over 36 months (salaries, missions, equipment)

Complex Phases in Ammonia-Water Mixtures Under Extreme Conditions: Disorder, Plasticity, and Super-Ionicity

Scientific context: The project aims to theoretically model the crystalline phases of ammonia-water mixtures and characterize the associated forms of atomic-scale disorder using molecular dynamics simulations. This understanding is crucial for planetary physics, as these mixtures are found in giant planets like Neptune and Uranus. Despite the recent experimental exploration of the phase diagram of these mixtures [1], simulating the associated phase transitions at the atomic level remains a challenge.
The structure of solid phases of water, ammonia, and their mixtures is governed by hydrogen bonds, resulting in rich polymorphism. Indeed, in mixed crystals, hydrogen bonds vary depending on donor/acceptor molecules and on conditions of temperature and pressure. At high-pressure, proton transfers leads to the appearance of ionic phases that are still poorly understood. Collaboration between theorists and experimentalists is essential : experimental techniques like X-ray diffraction and vibrational spectroscopies evidence various types of disorder (positional, orientational, dynamic/static, concentration-related) but their full interpretation requires comparison to atomic-scale simulations.
Missions: Given the extensive phase diagram of Ammonia-Water mixtures, the recruited person will focus on two main objectives: (i) characterizing the crystal to plastic phase transitions in Ammonia-water mixtures with different stoichiometries and (ii) exploring ionic (and possibly superionic) phases of ammonia hemi-hydrate (AHH).
(i) In particular, we will investigate if the coupling between orientational and translational disorder, that we recently evidenced in AHH [2], can also be at play in other mixtures. For this objective, improving the parametrization of existing interatomic force fields to describe the molecular phases at high pressure is crucial. Parametrization and assessment of the force fields can be done via Bayesian approaches, using DFT calculations as reference.
(ii) Addressing ionic phases will require developing accurate reactive interatomic potentials to describe ionization processes. Combining physical interactions and machine learning techniques [3] (using DFT data for training) should provide an accurate yet computationally affordable description.
The refined force fields will be integrated in highly parallel codes to perform large-scale Molecular Dynamics, to study the atomic dynamics and the stability of the different phases.

- Write reports and scientific papers on the results obtained.
- Participate in meetings concerning the project.
- Communicate the results via seminars or conferences.
- Ensure effective communication between theory and experiment.

- The candidate should have a PhD in physics, chemistry or a related field.
- The candidate should be creative, have good analytical skills and be highly motivated by computational work.

We have an opening for an 18-month fixed-term Postdoctoral Research Fellow position in theoretical and computational physics of ultracold atoms and hydrodynamics of quantum fluids in the research group of Professor Karen V. Kheruntsyan at the University of Queensland, Brisbane, Australia.

The position is funded by the ARC Discover Project “Hydrodynamics of quantum fluids” and will be at the Research Academic Level A. The postdoctoral fellow will work on fundamental aspects of finite-temperature out-of-equilibrium dynamics of ultracold atomic gases in quantum fluid regimes that can be described by effective hydrodynamic approaches.

The project is motivated by the so-called ``unreasonable effectiveness of hydrodynamics" when it is applied to characterise the out-of-equilibrium behaviour of quantum fluids. Examples here include electron currents in graphene, formation of quark-gluon plasma, and dynamics of ultra-cold quantum gases. The reasons behind the unexpected effectiveness of hydrodynamics in describing these profoundly quantum and physically disparate systems are not well understood. This project intends to develop a systematic understanding of this open question by developing new effective hydrodynamic theories of quantum fluids formed by ultracold atomic gases. More specifically, the aims of the project are:
Formulate new hydrodynamic theories of strongly interacting quantum gases and apply them to understand the out-of-equilibrium behaviour of such gases in hydrodynamic regimes at the Navier-Stokes scale.
Establish the range of validity of these theories by benchmarking them against other many-body methods, including exact numerical techniques where applicable.
Evaluate the thermal conductivity of interacting Bose and Fermi gases and determine the ensuing heat transport in various out-of-equilibrium scenarios.

Applicants will have (or will be in the process of obtaining) a PhD in theoretical physics in the research area of ultracold quantum gases, condensed matter physics, or computational fluid dynamics. Expertise in numerical methods for quantum many-body theory and computational fluid dynamics, such as finite temperature c-field techniques, truncated Wigner approximation, Matrix Product States, or PDE solvers for Navier-Stokes equations will be an advantage. Applicants should also have an emerging profile in the discipline area and evidence of high-quality publications in reputed peer-reviewed journals.

AI4Embryo: artificial intelligence for better human embryo quality assessment in reproductive medicine

Deadline: February 15th 2024
Application: CV, letter of motivation & 2 letters of recommendation to herve.turlier@college-de-france
Duration: 24 months, from Mar 2024
Place: Collège de France

Center for Interdisciplinary Research in Biology

11, place Marcelin Berthelot, 75005 Paris, FRANCE
Supervision: Dr. Hervé Turlier, team leader
Team: Multiscale Physics of Morphogenesis www.turlierlab.com Salary: between € 2,866 and € 4,204 gross monthly depending on experience

Activities: Infertility is a global health issue faced by about 10% of couples worldwide. Since the advent of in vitro fertilization (IVF) techniques, the selection of the best embryo to transfer remains a
major subject of research. Since two decades, medical incubators with embedded
timelapse microscopy imaging allow the recording of the preimplantation embryo
development until the blastocyst stage, and simplify the selection of embryo(s) by embryologists through the quantification of morphokinetic parameters, such as cleavage timings or blastocyst morphology. Recently, artificial intelligence (AI) algorithms have started being explored to automate the grading or selection of embryos, but they either don’t exploit all available imaging data (3D+time) or don’t combine it with patient’s health and incubation parameters. The research project aims at developing state-of-the-art deep-learning approaches to extract relevant morphokinetic features of human embryo development and, building on the expertise of the team in early mammalian embryo mechanics [1-3], in the development of image analysis tools tailored to early embryos [4-6] and on established collaborations with two reproductive medicine units in two large public hospitals in France.

The candidate must have already demonstrated the ability to publish in international peer-reviewed conferences or journals (postdoc) or a strong potential for research (engineer). No prior knowledge in biology or medicine is expected, but a strong will to collaborate with medical doctors and a genuine interest for biophysical modeling is necessary. Strong work autonomy, initiative and scientific curiosity are key assets for this position. Fluency in English, excellent communication skills and motivation for collaborative and interdisciplinary research are naturally expected.

Working environment: The successful candidate will be welcomed into the interdisciplinary team "Multiscale physics of morphogenesis" led by Hervé Turlier and composed of ~10 researchers. We are committed to establishing a welcoming place for all and fostering inclusion and diversity. The team is located at the Collège de France, in the heart of the Latin Quarter in Paris. Integrated within the PSL University, and close to other major institutions such as the Ecole Normale Supérieure and the Institut Curie, the Collège de France constitutes an exceptional scientific environment unique in the world.

Duration: 24 months, from Mar 2024 - possibility to extend to 36 months after evaluation
Salary: between € 2,992 and € 4,204 gross monthly depending on experience

Activities: The project focuses on developing inverse morphogenetic approaches to collective cellular behaviors, with a particular emphasis on early embryos and small tissues. The work will consist of exploring multicellular morphogenetic principles from a computational perspective coupling realistic physical models with machine learning approaches. The work will rely on powerful in-house models of multicellular mechanics and cell-cell signaling in 3D. The postdoctoral fellow will explore how growth, division, patterning, and cell cycle dynamics can sculpt embryos and tissues, and how these morphogenetic pathways and self-organisation principles can be learned from data or engineered in reverse. The research activities are part of the ERC DeepEmbryo project led by Hervé Turlier, whose goal is to reverse-engineer the development of embryos by combining biophysical and machine learning methods.

Missions: The successful candidate will build an optimization framework that couples internal 3D models of multicellular mechanics and cell-cell signaling with neural networks and train such a framework coupling classical optimizers and reinforcement learning approaches. She/he will implement this framework in Python and C++ and deploy it on the team's internal GPU/CPU cluster. He/she will explore morphogenetic pathways and shape emergence principles in silico with forward and inverse modeling approaches. She/he will have to work in collaboration with biologists and with the team's software engineers. She/he will have to present her/his results at scientific conferences, write scientific articles and actively participate in the scientific and social life of the team and of the host Institute.

Expected profile: The candidate must hold a PhD in applied mathematics, theoretical physics or computer science, demonstrate excellent computer science skills (python, C++) and have strong prior experience with deep learning methods. Experience or expertise in reinforcement learning will be an important asset and prior experience working with a high-performance computing cluster will be useful. The candidate must have already demonstrated the ability to publish in international peer-reviewed scientific journals or conferences. No prior knowledge of biology is expected, but a genuine interest in biological systems and morphogenesis is necessary. Prior experience of collaboration with biologists or biophysicists will be however considered very positively. Genuine work autonomy, initiative and scientific curiosity are key assets for this position. Fluency in English, good communication skills and motivation for research are naturally expected.
