Q-deformed fermionic Lipkin model at finite temperature
(1997-08-15)
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 ...

Fermionic entanglement in the Lipkin model
(American Physical Society, 2019-12)
We examine the fermionic entanglement in the ground state of the fermionic Lipkin model and its relation with bipartite entanglement. It is first shown that the one-body entanglement entropy, which quantifies the minimum ...
PHASE-TRANSITION IN A Q-DEFORMED LIPKIN MODEL
(Iop Publishing Ltd, 1995-09-07)
Assuming q-deformed commutation relations for the fermions, an extension of the standard Lipkin Hamiltonian is presented. The usual quasi-spin representation of the standard Lipkin model is also obtained in this q-deformed ...

Spectral explanation for statistical odd-even staggering in few fermions systems
(MDPI AG, 2021-03)
Odd-even statistical staggering in a Lipkin-like few fermions model has been recently encountered. Of course, staggering in nuclear binding energies is a well established fact. Similar effects are detected in other finite ...
