Nonequilibrium Dynamical Quantum Phase Transitions in the Extended Agassi Model
We investigate dynamical quantum phase transitions (DQPTs) in the extended Agassi model following sudden quenches of same level pairing ($\Sigma$), monopole-monopole ($\chi$) and cross level pairing ($\Lambda$) strengths. Using exact diagonalization, we characterize the non-equilibrium dynamics through the Loschmidt ec...
