Abstract
Liquid crystalline blue phase (BP) II sandwiched between a pair of confining surfaces with specifically designed patterns is studied using numerical simulation based on the Landau-de Gennes phenomenological approach. Directed by the surface patterns, quasi-two-dimensional half-Skyrmion lattices form. Specifically, we observe the formation of square and triangular lattices of half-Skyrmions. These lattices of the swirling skyrmion textures are interspersed with singular −1/2 or −1 line defects, which also constitute quasi-two-dimensional regular lattices. Finally, this work is a contribution to designing and stabilising complex birefringent layer profiles of various symmetries.
