A. Caille et al., GROUND-STATE PHASE-DIAGRAM OF A ONE-DIMENSIONAL DISCOTIC LIQUID-CRYSTAL IN A LOCAL ANISOTROPY-FIELD, Physical review. B, Condensed matter, 49(5), 1994, pp. 3104-3108
The ground-state phases of a chiral model which describes orientationa
l order of a single stack of planar objects with threefold symmetry su
bject to a local anisotropy field are examined. The results are used t
o interpret experimental data on columnar discotic liquid crystals whi
ch exhibit triangular arrays of helically ordered molecular stacks.
