The interplay between temperature and q-deformation in the phase transition properties of many-body systems is studied in the particular framework of the collective q-deformed fermionic Lipkin model. It is shown that in ...

The interplay between temperature and q-deformation in the phase transition properties of many-body systems is studied in the particular framework of the collective q-deformed fermionic Lipkin model. It is shown that in ...

We discuss the process of equilibrium?s attainment in an interacting many fermionssystem linked to a heat reservoir, whose temperature T is subject toa short-time disturbance of total duration 2τ . In this time-interval, ...

We consider a typical many body problem. In particular, we study an exactly solvable fermion system. We apply to it recently developed statistical quantifiers like the statistical complexity C and the disequilibrium D. The ...
