Dephasing in matter-wave interferometry
Fernando C. Lombardo, Paula I. Villar
We review different attempts to show the decoherence process in double-slit-like experiments both for charged particles (electrons) and neutral particles with permanent dipole mome…
Decoherence induced by a fluctuating Aharonov-Casher phase
Fernando C. Lombardo, Francisco D. Mazzitelli, Paula I. Villar
Dipoles interference is studied when atomic systems are coupled to classical electromagnetic fields. The interaction between the dipoles and the classical fields induces a time-var…
Decoherence induced by a composite environment
Fernando C. Lombardo, Paula I. Villar
We study the decoherence induced by the environment over a composite quantum system, comprising two coupled subsystems A and B, which may be a harmonic or an upside-down oscillator…
Decoherence, tunneling and noise-activation in a double-potential well at high and zero temperature
Nuno D. Antunes, Fernando C. Lombardo, Diana Monteoliva +1
We study the effects of the environment on tunneling in an open system described by a static double-well potential. We describe the evolution of a quantum state localized in one of…
Decoherence in composite quantum open systems: the effectiveness of unstable degrees of freedom
Fernando C. Lombardo, Paula I. Villar
The effect induced by an environment on a composite quantum system is studied. The model considers the composite system as comprised by a subsystem A coupled to a subsystem B which…
