Abstract

In this project we aim to study the quasi-probability distributions, particularly their domains of negative values, through the quantum trajectories derived from the Bohmian mechanics. The interaction between matter and the radiation field is also part of our interest. We intent to use this interaction firstly to analyze, through the Stern-Gerlach device, the possibility to achieve atomic lithography and next, to study the interaction between matter and the Casimir radiation. Among our goals is to analyze the possibility of increasing the rate of photon creation via dynamical Casimir effect due to the interaction between matter and the Casimir radiation. Finally, using an exact alternative treatment for the coupling between a quantum system and the reservoir, we propose to analyze the early relaxation process, for timescales significantly shorter than the system relaxation time.
