Dynamics of a time-dependent spin chain

ORAL

Abstract

We study the dynamics of a time-dependent quantum spin chain. We analytically determine the spin dynamics and find exotic discrete resonant peaks surfing above continuum spectrum from low to high energies. Those results are further confirmed by large-scale infinite time-evolving block decimation (iTEBD) calculation. Our results provide a practicable approach to go beyond integrability.
