Universal Long-Time Behavior of the Quantum Fisher Information in Dynamical Quantum Phase Transitions
J. Mumford, R. J. Lewis-Swan
We investigate dynamical quantum phase transitions (DQPTs) in quantum systems that possess well-defined classical limits, focusing on the spinor Bose-Einstein condensate and the Li…

Characterizing the transition from topology to chaos in a kicked quantum system
J. Mumford, H. -Y. Xie, R. J. Lewis-Swan
This work theoretically investigates the transition from topology to chaos in a periodically driven system consisting of a quantum top coupled to a spin-1/2 particle. The system is…
