Abstract: Abstract A novel mechanism is found in which the matter field is coupled to the electromagnetic ones without invoking the minimal coupling recipe. A quanto-electromagnetic field is derived that can induce charge and current to… read more here.

Abstract: A general procedure is established to calculate the quantum phase diagrams for finite matter-field Hamiltonian models. The minimum energy surface associated to the different symmetries of the model is calculated as a function of the… read more here.

DOI: 10.1103/physreva.99.062106
Abstract: This paper is devoted to the study of the Bayesian-inference approach in the context of estimating the dipole coupling strength in matter-field interactions. In particular, we consider the simplest model of a two-level system interacting… read more here.
