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…
Continuous Monitoring of Dynamical Systems and Master Equations
L. F. Lopes Oliveira, R. Rossi, A. R. Bosco de Magalhaes +2
We illustrate the equivalence between the non-unitary evolution of an open quantum system governed by a Markovian master equation and a process of continuous measurements involving…
Experimental proposal for measuring the Gouy phase of matter waves
I. G. da Paz, P. L. Saldanha, M. C. Nemes +1
The Schrödinger equation for an atomic beam predicts that it must have a phase anomaly near the beam waist analogous to the Gouy phase of an electromagnetic beam. We propose here a…
Residual entanglement and sudden death: A direct connection
J. G. Oliveira Junior, J. G. Peixoto de Faria, M. C. Nemes
We explore the results of [V. Coffman, et al., Phys. Rev. A 61 (2000) 052306] derived for general tripartite states in a dynamical context. We study a class of physically motivated…
Control of state and state entanglement with a single auxiliary subsystem
R. Rossi, A. R. Bosco de Magalhães, J. G. Peixoto de Faria +1
We present a strategy to control the evolution of a quantum system. The novel aspect of this protocol is the use of a \emph{single auxiliary subsystem}. Two applications are given,…
Indirect evidence for the Gouy phase for matter waves
I. G. da Paz, M. C. Nemes, C. H. Monken +2
We show that the well known geometric phase, the Gouy phase in optics can be defined for matter waves in vacuum as well. In particular we show that the underlying physics for the "…
