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…
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…
Some Aspects of Quantum Optics Using Light Fields in Traveling Waves
C. Valverde, A. N. Castro, E. P. Santos +1
Although the theoretical treatment to describe the light field in Quantum Optics was generic, during large time it was predominantly related to optical modes trapped inside cavitie…
Perfect transfer of quantum states in a network of harmonic oscillators
Dirceu Portes, Hilario Rodrigues, Sergio B. Duarte +1
This work presents an exactly soluble scheme to address the problem of optimal transfer of quantum states through a set of harmonic oscillators composing a network with connect…
