Dynamical phase transitions (DPTs) are generally defined under two different but related categories: DPT-I where the equilibrium value, or long-time average, of the order parameter as a function of the control parameter demonstrates a phase boundary; DPT-II where the Loschmidt return rate shows a cusp singularity in real-time dynamics. Here we follow up on a recent numerical demonstration [Phys. Rev. Lett. 121, 016801 (2018)] where out-of-time-order correlators (OTOC) of a single-site are shown…

Universal cooling dynamics towards a quantum critical point

We investigate the loss of adiabaticity when cooling a many-body quantum system from an initial thermal state towards a quantum critical point. The excitation density, which quantifies the degree of

Quantum Field Theory and Critical Phenomena

Introduced as a quantum extension of Maxwell's classical theory, quantum electrodynamic (QED) has been the first example of a quantum field theory (QFT). Eventually, QFT has become the framework for
