Resumen
We discuss the process of equilibrium’s attainment in an interacting manyfermions system linked to a heat reservoir, whose temperature T is subject to a short-time disturbance of total duration 2τ . In this time-interval, its temperature increases up to a maximum value M T , cooling off afterward (also gradually) to its original value. The process is described by a typical master equation that leads eventually to equilibration. We discuss how the equilibration process depends upon 1) the system’s fermion-number, 2) the fermionfermion interaction’s strength V, 3) the disturbance duration 2τ , and finally 4) the maximum number of equations N of the master equation.
