GKLS Vector Field Dynamics for Gaussian States
Hans Cruz-Prado, Octavio Castaños, Giuseppe Marmo +1
We construct the vector field associated to the GKLS generator for systems described by Gaussian states. This vector field is defined on the dual space of the algebra of operators,…
Fidelity, entropy, and Poincaré sections as tools to study the polyad breaking phenomena
M. Bermúdez-Montaña, R. Lemus, O. Castaños
The correlation diagram of the vibrational energy spectra associated with the stretching modes of triatomic molecules such as CO and HO is analyzed by means of two interact…
Searching for pairing energies in phase space
M. Calixto, O. Castaños, E. Romera
We obtain a representation of pairing energies in phase space, for the Lipkin-Meshkov-Glick and general boson Bardeen-Cooper-Schrieffer pairing models. This is done by means of a p…
Fidelity, susceptibility and critical exponents in the Dicke model
M. A. Bastarrachea-Magnani, O. Castaños, E. Nahmad-Achar +2
We calculate numerically the fidelity and its susceptibility for the ground state of the Dicke model. A minimum in the fidelity identifies the critical value of the interaction whe…
