The Freedericksz transition in a spatially varying magnetic field
Tianyi Guo, Xiaoyu Zheng, Peter Palffy-Muhoray
Much is known about the Freedericksz transition induced by uniform electric and magnetic fields in nematic liquid crystals. Here we study the effects of a spatially varying field o…

Impedance Matching in an Elastic Actuator
Tianyi Guo, Xiaoyu Zheng, Peter Palffy-Muhoray
We optimize the performance of an elastic actuator consisting of an active core in a host which performs mechanical work on a load. The system, initially with localized elastic ene…

Surface Anchoring Energy of Cholesteric Liquid Crystals
Tianyi Guo, Xiaoyu Zheng, Peter Palffy-Muhoray
In this paper, we propose a suitable surface energy expression for cholesteric liquid crystals. We show that there exists a symmetry allowed term for chiral nematics that doesn't a…
