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…

Entanglement Entropy on Fuzzy Spaces
Djamel Dou, Badis Ydri
We study the entanglement entropy of a scalar filed in 2+1 spacetime where space is modeled by a fuzzy sphere and a fuzzy disc. In both models we evaluate numerically the resulting…
