On the Feynman propagator on curved spacetimes




Faculty of Physics, University of Warsaw

February 28, 2024 12:30 PM

The Feynman propagator is one of the main tools of Quantum Field Theory. I will review various definitions of this concept, including the operator-theoretic and out-in Feynman propagator. I will discuss various examples of spacetimes:  stationary, asymptotically stationary, FLRW,  deSitter and anti-deSitter.

I will consider both the stable and tachyonic case.

Based on joint work with Christian Gass.
