Abstract

The emergent thermodynamics associated with quenching in the Heisenberg XY model is studied by calculating the fluctuations in the work done by an arbitrary quench. For certain post-quench parameters, non-analytic behavior in the work fluctuation as a function of pre-quench parameters can be used to locate the critical regions in the XY model phase diagram.
