Comment on "Quantum critical paraelectrics and the Casimir effect in time"
H. Chamati, N. S. Tonchev
At variance with the authors' statement [L. Pálová, P. Chandra and P. Coleman, Phys. Rev. B 79, 075101 (2009)], we show that the behavior of the universal scaling amplitude of the…
Generalized Mittag-Leffler functions in the theory of finite-size scaling for systems with strong anisotropy and/or long-range interaction
H. Chamati, N. S. Tonchev
The difficulties arising in the investigation of finite-size scaling in --dimensional O(n) systems with strong anisotropy and/or long-range interaction, decaying with the interp…
Finite-Size Scaling and Long-Range Interactions
N. S. Tonchev
The present review is devoted to the problems of finite-size scaling due to the presence of long-range interaction decaying at large distance as , where is the spati…
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…
