  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.
