The notion of a dynamical quantum phase transition (DQPT) was recently introduced [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)] as the nonanalytic behavior of the Loschmidt echo at critical times in the thermodynamic limit. In this work the quench dynamics in the ground state sector of the two-dimensional Kitaev honeycomb model is studied regarding the occurrence of DQPTs. For general two-dimensional systems of BCS type it is demonstrated how the zeros of the Loschmidt echo coalesce to…

The study of the rate function of the return probability has proven that the DMI does not affect the DQPT, and it is concluded that the ramping across the quantum critical point is not a necessary and sufficient condition for D QPT.

The interferometric phase approach unravels the possibility of occurrence of DQPTs which persists even up to a considerable loss of purity of the engineered initial state as long as a constraint relation involving the dissipative coupling and ramping time (rate) is satisfied.

It is shown analytically that the connection between the DPTs and the EPTs does not hold generally, and also no DPT by crossing the equilibrium critical point.
