Environmentally induced corrections to the geometric phase in a two-level system
Fernando C. Lombardo, Paula I. Villar
We calculate the geometric phase for different open systems (spin-boson and spin-spin models). We study not only how they are corrected by the presence of the different type of env…
Decoherence in a Two Slit Diffraction Experiment with Massive Particles
Paula I. Villar, Fernando C. Lombardo
Matter-wave interferometry has been largely studied in the last few years. Usually, the main problem in the analysis of the diffraction experiments is to establish the causes for t…
Visibility Fringe Reduction Due to Noise-Induced Effects: Microscopic Approach to Interference Experiments
Paula I. Villar, Fernando C. Lombardo
Decoherence is the main process behind the quantum to classical transition. It is a purely quantum mechanical effect by which the system looses its ability to exhibit coherent beha…
Macroscopic tunneling, decoherence and noise-induced activation
Fernando C. Lombardo, Diana Monteoliva, Paula I. Villar
We study the effects of the environment at zero temperature on tunneling in an open system described by a static double-well potential. We show that the evolution of the system in…
