Jonah Kudler-Flam ( IAS) “Horizons as eavesdroppers: decoherence from soft radiation”
Abstract: Recently, Danielson, Satishchandran, and Wald proposed a novel mechanism for decoherence in spacetimes with Killing horizons. When Alice performs a Stern-Gerlach type experiment outside the horizon, there is a fundamental rate of decoherence due to the emission of soft gravitons/photons that radiate away information. In this talk, I will sharpen and generalize this mechanism by recasting the gedankenexperiment in … Read More
