The Forced Soliton Equation and Semiclassical Soliton Form Factors
arXiv:2010.10381 · doi:10.1103/PhysRevLett.125.231601
Abstract
We show that the leading semiclassical behavior of soliton form factors at arbitrary momentum transfer is controlled by solutions to a new wave-like integro-differential equation that describes solitons undergoing acceleration. We work in the context of two-dimensional linear sigma models with kink solitons for concreteness, but our methods are purely semiclassical and generalizable.
