Theoretical investigation of helix distortion and dielectric spectrum of antiferroelectric liquid crystals

Landau–Ginzburg equation is utilized to investigate the dielectric spectrum of an antiferroelectric liquid crystal (AFLC). Two collective modes, one associated with the in-phase motion at the low frequency side and the other related with the anti-phase motion at the high frequency side, are discusse...
