Quantum States of a Skyrmion in a 2D Antiferromagnet

Abstract

Quantum states of a skyrmion in a 2D antiferromagnetic lattice are obtained by quantizing the scaling parameter of Belavin-Polyakov model. Skyrmion classical collapse due to violation of the translational invariance of the continuous spin-field model by the lattice is replaced in quantum mechanics by transitions between discrete energy levels of the skyrmion. Rates of transitions due to the emission of magnons are computed. Ways of detecting quantization of skyrmion states are discussed.
