The role of position momentum correlations in coherence freezing and purity behavior
Pedro P. da Silva, Carlos H. S. Vieira, Jonas F. G. Santos +3
We explore the effects of Markovian bath coupling and initial position-momentum correlations on the coherence and purity of Gaussian quantum states. Our analysis focuses on the rol…
Coherence behavior of strongly coupled bosonic modes
Jucelino F. Sousa, Carlos H. S. Vieira, Jonas F. G. Santos +1
We study the effect of the intermode coupling in the generation of coherence when two bosonic modes are bilinearly coupled. We consider the case for which the two modes are weakly…
Poisson's spot and Gouy phase
I. G. da Paz, Rodolfo Soldati, L. A. Cabral +2
Recently there have been experimental results on Poisson spot matter wave interferometry followed by theoretical models describing the relative importance of the wave and particle…
Atomic Focusing by Quantum Fields: Entanglement Properties
I. G. da Paz, H. M. Frazão, M. C. Nemes +1
The coherent manipulation of the atomic matter waves is of great interest both in science and technology. In order to study how an atom optic device alters the coherence of an atom…
Position-momentum correlations in matter waves double-slit experiment
J. S. M. Neto, I. G. da Paz, L. A. Cabral
We present a treatment of the double-slit interference of matter-waves represented by Gaussian wavepackets. The interference pattern is modelled with Green's function propagator wh…
