Scattering, bound states, and resonances in the one-dimensional Dirac equation via supersymmetric quantum mechanics
Camila C. Soares, Luis B. Castro, Antonio S. de Castro
We develop a unified treatment of scattering and discrete spectra for the one-dimensional Dirac equation with scalar and vector interactions. Under the spin-symmetry condition, the…
Dispersive Jaynes-Cummings Hamiltonian describing a two-level atom interacting with a two-level single mode field
C. J. S. Ferreira, C. Valverde, B. Baseia
We investigate the time evolution of statistical properties of a single mode radiation field after its interaction with a two-level atom. The entire system is described by a disper…
On the paradoxical evolution of the number of photons in a new model of interpolating Hamiltonians
C. Valverde, B. Baseia
We introduce a new Hamiltonian model which interpolates between the Jaynes-Cummings model and other types of such Hamiltonians. It works with two interpolating parameters, rather t…
A large class of bound-state solutions of the Schrödinger equation via Laplace transform of the confluent hypergeometric equation
P. H. F. Nogueira, A. S. de Castro, D. R. M. Pimentel
It is shown that analytically soluble bound states of the Schrödinger equation for a large class of systems relevant to atomic and molecular physics can be obtained by means of the…
Controlling properties of a hybrid Cooper pair box interacting with a nanomechanical resonator in the presence of Kerr nonlinearities and losses
C. Valverde, A. N. Castro, B. Baseia
We consider the Jaynes-Cummings model describing the interaction of a Cooper pair box (CPB) and a nanoresonator (NR) in the presence of a Kerr medium and losses The evolution of th…
Controlling the nonclassical properties of a hybrid Cooper pair box system and an intensity dependent nanomechanical resonator
C. Valverde, V. G. Gonçalves, B. Baseia
We employ a more realistic treatment to investigate the entropy and the excitation-inversion of a coupled system that consists of a nanomechanical resonator and a superconducting C…
