Multiple-scale analysis of open quantum systems
D. N. Bernal-García, B. A. Rodríguez, H. Vinck-Posada
In this work, we present a multiple-scale perturbation technique suitable for the study of open quantum systems, which is easy to implement and in few iterative steps allows us to…
What can we learn from the dynamics of entanglement and quantum discord in the Tavis-Cummings model?
Juliana Restrepo, Boris A. Rodriguez
We revisit the problem of the dynamics of quantum correlations in the exact Tavis-Cummings model. We show that many of the dynamical features of quantum discord attributed to dissi…
Decoherence and entanglement in tripartite systems: Cavity QED
E. Agudelo, B. A. Rodriguez, K. M. Fonseca-Romero
We propose an experimental setup, feasible with present day technology, involving two highquality- factor cavities, one Ramsey zone and a two-level atom which interacts with them.…
Nonlinear QM as a fractal Brownian motion with complex diffusion constant
Carlos Castro, Jorge Mahecha, Boris Rodriguez
A new nonlinear Schroedinger equation is obtained explicitly from the fractal Brownian motion of a massive particle with a complex-valued diffusion constant. Real-valued energy (mo…
