Fixed Points and Dynamic Topological Phenomena in a Parity-Time-Symmetric Quantum Quench
We identify dynamic topological phenomena such as dynamic Chern numbers and dynamic quantum phase transitions in quantum quenches of the non-Hermitian Su-Schrieffer-Heeger Hamiltonian with parity-time [Formula: see text] symmetry. Their occurrences in the non-unitary dynamics are intimately connecte...
