GARCIA-MELGAREJO, J. C. et al. A Numerical Perspective on the Jaynes-Cummings Model Wigner Function. Comp. y Sist. [online]. 2019, vol.23, n.3, pp.1125-1132.  Epub 09-Ago-2021. ISSN 2007-9737.  https://doi.org/10.13053/cys-23-3-3136.

The Wigner function appeared to discuss the quantum correction of thermodynamic equilibrium, and it has become a tool for the analysis of quantum systems, especially the harmonic oscillator, which states describe the quantum field in a cavity. We discuss a matrix approach for the computation of the Wigner function. The numerical techniques here discussed are applied to obtain the time-dependent Wigner function of the field for the Jaynes-Cummings Model, which is widely known to describe the fundamental matter-field interactions in a perfect cavity.

Palabras llave : Wigner function; Jaynes-Cummings model.
