Finite-Bandwidth Protection of a Three-Level Quantum Heat Engine Against Parasitic Heat Leaks
Gilberto Aparecido Prataviera, Marcos César de Oliveira
Finite-bandwidth reservoir engineering can suppress unwanted transitions in a quantum thermal machine, but a physical filter also introduces a finite response time. We study this c…
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,…
Temperature estimation of an entangled pair of trapped ions
O. P. de Sá Neto, H. A. S. Costa, G. A. Prataviera +1
We apply estimation theory to a system formed by two interacting trapped ions. By using the Fisher matrix formalism, we introduce a simple scheme for estimation of the temperature…
Phase collapse and revival of a 1-mode Bose-Einstein condensate induced by an off-resonant optical probe field and superselection rules
L. G. E. Arruda, G. A. Prataviera, M. C. de Oliveira
Phase collapse and revival for Bose-Einstein condensates is a nonlinear phenomena appearing due atomic collisions. While it has been observed in a general setting involving many mo…
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…
Many-particle Sudarshan-Lindblad equation: mean-field approximation, nonlinearity and dissipation in a spin system
G. A. Prataviera, S. S. Mizrahi
A system of spin-1/2 particles interacting with a thermal reservoir is used as a pedagogical example for advanced undergraduate and graduate students. We introduce and illustra…
