Theory HEP SeminarNon-adiabatic and non-local behavior in effective theoriesMartin BojowaldPenn StateQuantum dynamics is in general non-local, but common effective theories often use derivative expansions that imply local approximations. This talk introduces a direct description of non-local effects at a semiclassical level in various cosmological scenarios, based on an application of non-adiabatic quantum dynamics as used for instance in quantum chemistry. Systems considered include tunnelling phenomena, a new observationally consistent version of Higgs inflation, and cosmological back-reaction effects.
