Dynamics, quantum states and Compton scattering in nonlinear gravitational waves
Year: 2024
Type: article
Abstract: A bstract The classical dynamics and the construction of quantum states in a plane wave curved spacetime are examined, paying particular attention to the similarities with the case of an electromagnetic plane wave in flat spacetime. A natural map connecting the dynamics of a particle in the Rosen metric and the motion of a charged particle in an electromagnetic plane wave is unveiled. We then discuss how this map can be translated into the quantum description by exploiting the large number of underlying symmetries. We examine the complete analogy between Volkov solutions and fermion states in the Rosen chart and properly extend this to massive vector bosons. We finally report the squared S -matrix element of Compton scattering in a sandwich plane wave spacetime in the form of a two-dimensional integral.
