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…
Spacetime quantization induced by axial currents
S. Carneiro, M. C. Nemes
In the present contribution we show that the introduction of a conserved axial current in electrodynamics can explain the quantization of electric charge, inducing at the same time…
Searching for Decoherence-Free Subspaces in Cavity Quantum Electrodynamics
A. R. Bosco de Magalhães, M. C. Nemes
We construct a model which describes a recently performed experiment (Phys. Rev. A 64, 050301(R) (2001)) in which an entangled state between two modes of a single cavity is built.…
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…
Towards the understanding of Decoherence on Ion Traps
M. O. Terra Cunha, M. C. Nemes
Two mechanisms of decoherence in ion traps are studied, specially related to the experiment [Kielpinski et al., Science 291 (2001) 1013]. Statistical hypothesis are made about the…
