Quantum turbulence, superfluidity, non-Markovian dynamics, and wave function thermalization
Abstract
While quantum turbulence has been addressed both experimentally (predominantly for superfluid $^4$He and $^3$He) and theoretically, the dynamics of various ensembles of quantized vortices was followed in time only until the vortices decay into phonons. How this ``thermalization'' is achieved is still an unelucidated question. Here, we report on the microscopic treatment of the real-time dynamics of an initial ensemble of quantized vortices and anti-vortices, with no phonons, at zero temperature, in a Unitary Fermi Gas (UFG). We follow the system in time until ``thermalization'' is achieved, and a clear non-Markovian evolution of the single particle occupation probabilities is observed.
