Detecting non-equilibrium instabilities in the entanglement entropy of few-body systems


  • Mr. Joshua MCKENNEY

Primary authors



Entanglement entropy provides a quantitative measure of quantum purity in a quantum system. In this work, lattice methods are used to exactly solve non-relativistic, interacting few-body systems in one dimension. Focus is placed on the time-dependent dynamics of the entanglement entropy, particularly around externally driven resonances. The entanglement entropy is found to provide a robust indicator for unstable regions in such systems.
