Abstract:

In this talk, I will discuss how matter systems can lose quantum coherence by interacting with an environment consisting of low-energy photons or gravitons. This process will be illustrated using a simple model of an interferometry experiment. I'll focus particularly on how earlier results - which identified a relationship between "soft" photons/gravitons and boundary terms in the electromagnetic and gravitational matter currents - allows one to easily quantify precisely how much decoherence is caused by "leading" and "sub-leading" soft radiation.
