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…
Monte Carlo Simulation of a NC Gauge Theory on The Fuzzy Sphere
Denjoe O'Connor, Badis Ydri
We find using Monte Carlo simulation the phase structure of noncommutative U(1) gauge theory in two dimensions with the fuzzy sphere S^2_N as a non-perturbative regulator. There ar…
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…
