Topological classification of dynamical phase transitions
Szabolcs Vajna, Balázs Dóra
Dynamical phase transitions (DPT) are characterized by nonanalytical time evolution of the dynamical free energy. For general 2-band systems in one and two dimensions (eg. SSH mode…

Nematic, topological and Berry phases when a flat and a parabolic band touch
Balázs Dóra, Igor F. Herbut, Roderich Moessner
A (single flavor) quadratic band crossing in two dimensions is known to have a generic instability towards a quantum anomalous Hall (QAH) ground state for infinitesimal repulsive i…

Disentangling dynamical phase transitions from equilibrium phase transitions
Szabolcs Vajna, Balázs Dóra
Dynamical phase transitions (DPT) occur after quenching some global parameters in quantum systems and are signalled by the non-analytical time evolution of the dynamical free energ…
