On spin-squeezed states and their application to semi-classical kink dynamics in magnetic chains

H. Frahm, J. A. Holyst

Abstract

The authors introduce an extension of the Radcliffe spin-coherent state approach which incorporates squeezing effects to analyse semi-classical equations of motion for spin chains with different symmetries. A kink-solution instability against fluctuations in the complex squeeze parameter is found and quantum corrections to the kink energy are estimated.
