Quench dynamics of the Heisenberg chain

ORAL

Abstract

We study the time evolution of the one dimensional Heisenberg chain after a quench from strongly (anti-)ferromagnetic coupling to the isotropic point ($\Delta=1$). We generalize the Yudson integral representation for arbitrary states to the Heisenberg model and use it to study time-evolution of observables and correlation functions.
