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.
