Optimisation of Thimble Simulations and Quantum Dynamics of Multiple Fields in Real Time

High Energy Physics - Theory 2022-04-22 v1

Abstract

We apply the Generalised Thimble approach to the computation of exact path integrals and correlators in real-time quantum field theory. We first investigate the details of the numerical implementation and ways of optimizing the algorithm. We subsequently apply the method to an interacting two-field system in 0+1 dimensions, illustrating the scope for addressing realistic physical processes using real-time Generalised Thimble computations.
