Lower and upper bounds on the fidelity susceptibility
J. G. Brankov, N. S. Tonchev
We derive upper and lower bounds on the fidelity susceptibility in terms of macroscopic thermodynamical quantities, like susceptibilities and thermal average values. The quality of…

Quantum critical scaling and the Gross-Neveu model in 2+1 dimensions
H. Chamati, N. S. Tonchev
The quantum critical behavior of the 2+1 dimensional Gross--Neveu model in the vicinity of its zero temperature critical point is considered. The model is known to be renormalisabl…

Critical behavior of systems with long-range interaction in restricted geometry
H. Chamati, 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 , . The attention i…
