Finite-size effects in the spherical model of finite thickness
H. Chamati
A detailed analysis of the finite-size effects on the bulk critical behaviour of the -dimensional mean spherical model confined to a film geometry with finite thickness is r…
First order phase transitions in classical lattice gas spin models
H Chamati, S Romano
The present paper considers some classical ferromagnetic lattice--gas models, consisting of particles that carry --component spins () and associated with a --dimension…
Berezinskii-Kosterlitz-Thouless transition in two-dimensional lattice gas models
H Chamati, S Romano
We have considered two classical lattice-gas models, consisting of particles that carry multicomponent magnetic momenta, and associated with a two-dimensional square lattices; each…
The black-body radiation in Tsallis statistics
H. Chamati, A. Ts. Djankova, N. S. Tonchev
Some results for the black-body radiation obtained in the context of the -thermostatistics are analyzed on both thermodynamical and statistical-mechanical levels. Since the ther…
Some new exact critical-point amplitudes
H. Chamati, D. M. Danchev, N. S. Tonchev
The scaling properties of the free energy and some of universal amplitudes of a group of models belonging to the universality class of the quantum nonlinear sigma model and the O(n…
