Decoherence and localization in the double well model
Gabriela Barreto Lemos, M. F. Santos, J. G. Peixoto de Faria +2
We use a spin-1/2 model to analyze tunnelling in a double well system coupled to an external reservoir. We consider different noise sources such as fluctuations on the height and c…
Two cavity modes in a dissipative environment: cross decay rates and robust states
R. Rossi, A. R. Bosco de Magalhães, M. C. Nemes
We investigate the role of the cross decay rates in a system composed by two electromagnetic modes interacting with the same reservoir. Two feasible experiments sensitive to the ma…
Timescales for decoherence and dissipation: reasons for the success of master equations
M. O. Terra Cunha, S. Geraij Mokarzel, J. G. Peixoto de Faria +1
A perturbative treatment of reduced density operators of quantum subsystems is implemented in the same spirit as Fermi Golden Rule for scattering. Analytic expressions for linear e…
Decay rate and decoherence control in coupled dissipative cavities
A. R. Bosco de Magalhaes, S. G. Mokarzel, M. C. Nemes +1
We give a detailed account of the derivation of a master equation for two coupled cavities in the presence of dissipation. The analytical solution is presented and physical limits…
