Theoretical study on optical properties of liquid crystalline Skyrmion lattice

摘要

A chiral liquid crystal sandwiched by two parallel plates has been shown to exhibit various exotic structuresincluding a hexagonal lattice of Skyrmion excitations. Here we focus on the optical properties of a hexagonalSkyrmion lattice and present our theoretical studies based on direct numerical solving of Maxwell equations forlight waves. Specically, we discuss Kossel diagrams and optical microscope images of a hexagonal Skyrmionlattice and other structures resembling a thin slice of a bulk blue phase structure.
