Generalized Purity and Quantum Phase Transition for Bose-Einstein condensates in a Symmetric Double Well
Thiago F. Viscondi, K. Furuya, M. C. de Oliveira
The generalized purity is employed for investigating the process of coherence loss and delocalization of the Q-function in the Bloch sphere of a two-mode Bose-Einstein condensate i…
Non-Gaussian two-mode squeezing and continuous variable entanglement of linearly and circularly polarized light beams interacting with cold atoms
R. J. Missori, M. C. de Oliveira, K. Furuya
We investigate how entangled coherent states and superpositions of low intensity coherent states of non-Gaussian nature can be generated via non-resonant interaction between either…
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…
Modelling of Optical Detection of Spin-Polarized Carrier Injection into Light-Emitting Devices
M. C. de Oliveira, He Bi Sun
We investigate the emission of multimodal polarized light from Light Emitting Devices due to spin-aligned carriers injection. The results are derived through operator Langevin equa…
A consistent quantum model for continuous photodetection processes
M. C. de Oliveira, S. S. Mizrahi, V. V. Dodonov
We are modifying some aspects of the continuous photodetection theory, proposed by Srinivas and Davies [Optica Acta 28, 981 (1981)], which describes the non-unitary evolution of a…
Continuous Measurement of Atom-Number Moments of a Bose-Einstein Condensate by Photodetection
G. A. Prataviera, M. C. de Oliveira
We propose a measurement scheme that allows determination of even-moments of a Bose-Einstein condensate (BEC) atom number, in a ring cavity, by continuous photodetection of an off-…
