Previous works of our team have highlighted the great sensitivity of mixtures of neutral and dipolar particles to external fields, which can lead to original behavior like field-induced population inversion and peculiar dynamics [1]-[2]. More recently, a study by our team [3] has drawn attention to an unexpected result of the effect of composition on the bulk order transition. The intended work shall deepen these observations, in confined phase as well.
