Dynamics of Coherent States in Regular and Chaotic Regimes of the Non-integrable Dicke Model
S. Lerma-Hernández, J. Chávez-Carlos, M. A. Bastarrachea-Magnani +2
The quantum dynamics of initial coherent states is studied in the Dicke model and correlated with the dynamics, regular or chaotic, of their classical limit. Analytical expressions…
Covariant perturbations in the gonihedric string model
Efrain Rojas
We provide a covariant framework to study classically the stability of small perturbations on the so-called gonihedric string model by making precise use of variational techniques.…
Analytical description of the survival probability of coherent states in regular regimes
Sergio Lerma-Hernández, Jorge Chávez-Carlos, Miguel A. Bastarrachea-Magnani +2
Using coherent states as initial states, we investigate the quantum dynamics of the Lipkin-Meshkov-Glick (LMG) and Dicke models in the semi-classical limit. They are representative…
Accelerated and decelerated expansion in a causal dissipative cosmology
Miguel Cruz, Norman Cruz, Samuel Lepe
In this work we explore a new cosmological solution for an universe filled with one dissipative fluid, described by a barotropic EoS , in the framework of the full Israel-S…
Phantom solution in a non-linear Israel-Stewart theory
Miguel Cruz, Norman Cruz, Samuel Lepe
In this paper we present a phantom solution with a big rip singularity in a non-linear regime of the Israel-Stewart formalism. In this framework it is possible to extend this causa…
