Chaos, stability and quantum-classical correspondence in spin systems
Presenting Author: Shohini Ghose, Wilfrid Laurier University
Classical chaos is characterized by extreme sensitivity of a system's dynamics to small perturbations in initial conditions. At the quantum level, a similar characterization of chaos remains a challenge due to the uncertainty principle and the apparent linearity of quantum evolution. We have explored the question of quantum chaos in spin systems both theory and experiments. Various signatures of chaos and classical bifurcations can be observed in a deeply quantum regime as well as the semiclassical regime. Chaos can affect quantum phenomena such as entanglement and fidelity decay that play important roles in quantum information processing. We present a method to quantify the Bohr correspondence principle in chaotic systems, and explain previous conflicting results regarding the connection between chaos and entanglement.
