Dissipation driven dynamical topological phase transitions in two-dimensional superconductors

Abstract: By quenching the interaction strength, we induce and study a topological dynamical phase transition between superconducting phases of a planar fermionic model. Using the Lindblad Master Equation approach to account for the interactions of Bogoliubov quasiparticles among themselves and with the fluctuations of the superconducting order parameter, we derive the corresponding relaxation dynamics of the order parameter. To fully characterize the phase transition, we also compute the fidelity and the spin-Hall conductance of the system.
