Numerical investigation of the quantum fluctuations of optical fields transmitted through an atomic medium
A. Lezama, P. Valente, H. Failache +2
We have numerically solved the Heisenberg-Langevin equations describing the propagation of quantized fields through an optically thick sample of atoms. Two orthogonal polarization…
Order parameter for the dynamical phase transition in Bose-Einstein condensates with topological modes
E. R. F. Ramos, L. Sanz, V. I. Yukalov +1
In a trapped Bose-Einstein condensate, subject to the action of an alternating external field, coherent topological modes can be resonantly excited. Depending on the amplitude of t…
The quest for three-color entanglement: experimental investigation of new multipartite quantum correlations
K. N. Cassemiro, A. S. Villar, M. Martinelli +1
We experimentally investigate quadrature correlations between pump, signal, and idler fields in an above-threshold optical parametric oscillator. We observe new quantum correlation…
Storing quantum states in bosonic dissipative networks
M. A. de Ponte, S. S. Mizrahi, M. H. Y. Moussa
Considering a network of dissipative quantum harmonic oscillators we deduce and analyze the optimum topologies which are able to store, for the largest period of time, a quantum su…
Dynamical invariants and nonadiabatic geometric phases in open quantum systems
M. S. Sarandy, E. I. Duzzioni, M. H. Y. Moussa
We introduce an operational framework to analyze non-adiabatic Abelian and non-Abelian, cyclic and non-cyclic, geometric phases in open quantum systems. In order to remove the adia…
A general treatment of geometric phases and dynamical invariants
E. I. Duzzioni, R. M. Serra, M. H. Y. Moussa
Based only on the parallel transport condition, we present a general method to compute Abelian or non-Abelian geometric phases acquired by the basis states of pure or mixed density…
