“…[25][26][27][28][29][30][31][32] Eq. ( 1) thus provides a natural theoretical framework for the description of smoothly modulated nematic phases, and has been successfully used in recent years for the analytical 59,60 and numerical 59,61 modelling of a number of experimentally-relevant systems. However, its main shortcoming lies in the coarse-graining of all bulk particle properties into the three K i scalars -understood as free parameters arising from basic mean-field symmetries, and often taken to be equal for the sake of simplicity.…”

“…Instead of treating the active gel through a theory based on the LEP formulation for liquid crystals [4][5][6], we include the corresponding terms into the Beris-Edwards theory that uses Q-tensors to describe liquid crystals and is a popular field of research across the theoretical literature [23,[42][43][44][45], see also the recent overviews [46,47], as a more general alternative theory for liquid crystals. In a subsequent step, we express the two-dimensional Q-tensor in terms of the director field and an additional scalar order parameter to obtain an Ericksen-type model introduced in [38], for which we then derive the thin-film model in §3.…”

“…This hydrolysis of ATP fuels the molecular motors (and is also used for the polymerization and depolymerization of the actin filaments). Instead of treating the chemical potential difference as a local quantity or a fixed constant as is done for the Leslie-Ericksen-Prodi formulation [12,24,25], we include the corresponding terms into the Beris-Edwards theory that uses Q-tensors and is popular in the liquid crystal literature [11,16,29,53,54] nd the recent overview [2,28] as a more general alternative theory for liquid crystals. In a subsequent step, we express the Q-tensor in terms of the director field and an additional scalar order parameter to obtain the Ericksen model, for which we then derive the thin film model in section 3.…”
