Mathematical Physics Seminar
After a short general review of typical examples of "effective quantum dynamics" I focus on a study
of the effects of thermal noise on the motion of a quantum particle in a random potential.
I review a result appearing in joint work with Jeffrey Schenker that says that thermal noise
always destroys Anderson localization and leads to diffusive motion.
Subsequently, I describe results concerning the dynamics of a simple quantum-mechanical system
undergoing repeated measurements. "Purification" and the appearance of "quantum jumps" are analyzed.
