New Coherent String States and Minimal Uncertainty in WZWN Models
A. L. Larsen, N. Sánchez
We study the properties of {\bf exact} (all level ) quantum coherent states in the context of string theory on a group manifold (WZWN models). Coherent states of WZWN models may…
Quantum Coherent String States in AdS_3 and SL(2,R) WZWN Model
A. L. Larsen, N. Sánchez
In this paper we make the connection between semi-classical string quantization and exact conformal field theory quantization of strings in 2+1 Anti de Sitter spacetime. More preci…
New dual relations between quantum field theory and string regimes in curved backgrounds
M. Ramon Medrano, N. Sanchez
A {\cal R} "dual" transform is introduced which relates Quantum Field Theory and String regimes, both in a curved background with D-non compact dimensions. This operation maps the…
The Statistical Mechanics of the Self-Gravitating Gas: Equation of State and Fractal Dimension
H. J. de Vega, N. S'anchez
We provide a complete picture of the self-gravitating non-relativistic gas at thermal equilibrium using Monte Carlo simulations (MC), analytic mean field methods (MF) and low densi…
From the WZWN Model to the Liouville Equation: Exact String Dynamics in Conformally Invariant AdS Background
A. L. Larsen, N. Sánchez
It has been known for some time that the SL(2,R) WZWN model reduces to Liouville theory. Here we give a direct and physical derivation of this result based on the classical string…
Quantum String Dynamics in the conformal invariant SL(2,R) WZWN Background: Anti-de Sitter Space with Torsion
H. J. de Vega, A. L. Larsen, N. Sánchez
We consider classical and quantum strings in the conformally invariant background corresponding to the SL(2,R) WZWN model. This background is locally anti-de Sitter spacetime with…
