Semiclassical (QFT) and Quantum (String) anti - de Sitter Regimes: New Results
A. Bouchareb, M. Ramon Medrano, N. G. Sanchez
We compute the quantum string entropy S_s(m, H) from the microscopic string density of states of mass m in Anti de Sitter space-time. For high m, (high Hm -->c/α'), no phase transi…

The One-Plaquette Model Limit of NC Gauge Theory in 2D
Badis Ydri
It is found that noncommutative U(1) gauge field on the fuzzy sphere S^2_N is equivalent in the quantum theory to a commutative 2-dimensional U(N) gauge field on a lattice with two…
