Directed Motion of Liquid Crystal Skyrmions With Oscillating Fields

A. Duzgun,
C. Nisoli,
C. J. O. Reichhardt
et al.

Abstract: Using continuum simulations, we show that under a sinusoidal electric field, liquid crystal skyrmions undergo periodic shape oscillations which produce controlled directed motion. The speed of the skyrmion is non-monotonic in the frequency of the applied field, and exhibits multiple reversals of the motion as a function of changing frequency. We map out the dynamical regime diagram of the forward and reverse motion for two superimposed ac driving frequencies, and show that the reversals and directed motion can… Show more
