Relaxation and entropy generation after quenching quantum spin chains
M. Lencses, O. Pomponio, G. Takacs
This work considers entropy generation and relaxation in quantum quenches in the Ising and -state Potts spin chains. In the absence of explicit symmetry breaking we find univers…

Quasi-particle spectrum and entanglement generation after a quench in the quantum Potts spin chain
O Pomponio, L. Pristyak, G. Takacs
Recently, a non-trivial relation between the quasi-particle spectrum and entanglement entropy production was discovered in non-integrable quenches in the paramagnetic Ising quantum…
