Molecular geometry, twist-bend nematic phase and unconventional elasticity: a generalised Maier–Saupe theory

C Greco, GR Luckhurst, A Ferrarini - Soft Matter, 2014 - pubs.rsc.org
It has been found that bent-shaped achiral molecules can form a liquid crystal phase, called
the Twist-Bend Nematic (NTB), which is locally polar and spontaneously twisted having a …

Electrooptic response of chiral nematic liquid crystals with oblique helicoidal director

J Xiang, SV Shiyanovskii, C Imrie, OD Lavrentovich - Physical Review Letters, 2014 - APS
