Generation of generalized coherent states with two coupled Bose-Einstein condensates
L. Sanz, M. H. Y. Moussa, K. Furuya
We present a scheme to prepare generalized coherent states in a system with two species of Bose-Einstein condensates. First, within the two-mode approximation, we demonstrate that…
Quantum Entanglement and fixed point Hopf bifurcation
M. C. Nemes, K. Furuya, G. Q. Pellegrino +3
We present the qualitative differences in the phase transitions of the mono-mode Dicke model in its integrable and chaotic versions. We show that a first order phase transition occ…
Entanglement, chaos and atomic Wigner function of the Dicke model
L. Sanz, K. Furuya
We calculate the atomic (spin) Wigner function for the single mode Dicke model in the regime of large number of two-level atoms. The dynamics of this quasi-probability function on…
Entanglement versus mixedness for coupled qubits under a phase damping channel
E. S. Cardoso, M. C. de Oliveira, K. Furuya
Quantification of entanglement against mixing is given for a system of coupled qubits under a phase damping channel. A family of pure initial joint states is defined, ranging from…
