Timescales, dynamical phase transitions and 3rd order phase transitions in the 1d anisotropic XY model

Understand

Recent research into time-integrated observables has revealed a special class of states which cap- ture the singular features of the generating functions of those observables, as estimated by full counting statistics (FCS).

• In this work we extend the results of [Phys.
• Rev.
• B 87 184303 (2013)] to the 1d anisotropic XY -model and find a set of FCS critical points associated with the time-integrated transverse magnetization and anisotropy.
