A ferrroelectric nematic phase is desirable both from a practical and theoretical viewpoint, but experimentally it has yet to be observed. Mathematically, such a phase in polar mesogens could be described in a similar way to the Landau-De Gennes Q-tensor theory, but importantly disrespecting the typical head-to-tail symmetry, so that a second order parameter representing the polarisation of the state enters into the model. This talk is concerned with designing a model in terms of these moments that respects the physicality of order parameters.
