Collective Dissipation and Parameter Sensitivity in Trapped Ions Coupled to a Common Thermal Reservoir
C. F. P. Avalos, G. A. Prataviera, M. C. de Oliveira
We investigate the dynamics of two trapped ions interacting with a common thermal reservoir, focusing on how cross-correlated dissipation influences heating, steady-state behavior,…
Susceptibility of a two-level atom near an isotropic photonic band edge: transparency and band edge profile reconstruction
G. A. Prataviera, M. C. de Oliveira
We discuss the necessary conditions for a two-level system in the presence of an isotropic band edge to be transparent to a probe laser field. The two-level atom is transparent whe…
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…
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…
