In this talk, I will briefly review the worldline effective field theory (EFT) formalism for classical gravitational physics. Using worldline EFT, I will provide a framework for understanding the gravitational…
Interference is one of the most universal phenomena in nature, as exemplified by the real-time Feynman path integral. Despite the ubiquity of interference patterns, their evaluation has often proven challenging.…
I discuss work in progress on obtaining a reasonable density matrix of the universe in two dimensional quantum cosmology. I will do so by comparing aspects of the Hilbert space of closed universes in JT gravity…
