Critical properties of Sudden Quench Dynamics in the anisotropic XY Model
Critical properties of Sudden Quench Dynamics in the anisotropic XY Model
Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China(Dated: January 6, 2010)We study the zero temperature quantum dynamical critical behavior of the anisotropic XY chainunder a sudden quench in a transverse field. We demonstrate theoretically that both quench mag-netic susceptibility and two-particle quench correlation can be used to describe …
