Two-time Green's functions and spectral density method in nonextensive quantum statistical mechanics
A. Cavallo, F. Cosenza, L. De Cesare
We extend the formalism of the thermodynamic two-time Green's functions to nonextensive quantum statistical mechanics. Working in the optimal Lagrangian multipliers representation,…
The Classical Spectral Density Method at Work: The Heisenberg Ferromagnet
A. Cavallo, F. Cosenza, L. De Cesare
In this article we review a less known unperturbative and powerful many-body method in the framework of classical statistical mechanics and then we show how it works by means of ex…
Spectral density method in quantum nonextensive thermostatistics and magnetic systems with long-range interactions
A. Cavallo, F. Cosenza, L. De Cesare
Motived by the necessity of explicit and reliable calculations, as a valid contribution to clarify the effectiveness and, possibly, the limits of the Tsallis thermostatistics, we f…
Thermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet with long-range interactions via the spectral density method
A. Cavallo, F. Cosenza, L. De Cesare
The thermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet, with long-range interactions decaying as and in the presence of an external magnet…
