A singularity problem for interacting massive vectors
Zong-Gang Mou, Hong-Yi Zhang
Interacting massive spin-1 fields have been widely used in cosmology and particle physics. We obtain a new condition on the validity of the classical limit of these theories relate…
Optimisation of Thimble Simulations and Quantum Dynamics of Multiple Fields in Real Time
Simon Woodward, Paul M. Saffin, Zong-Gang Mou +1
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 nume…
Statistics on Lefschetz thimbles: Bell/Leggett-Garg inequalities and the classical-statistical approximation
Peter Millington, Zong-Gang Mou, Paul M. Saffin +1
Inspired by Lefschetz thimble theory, we treat Quantum Field Theory as a statistical theory with a complex Probability Distribution Function (PDF). Such complex-valued PDFs permit…
Simulations of a bubble wall interacting with an electroweak plasma
Zong-Gang Mou, Anders Tranberg, Paul M. Saffin
We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which…
Quantum tunnelling, real-time dynamics and Picard-Lefschetz thimbles
Zong-Gang Mou, Paul M. Saffin, Anders Tranberg
We follow up the work, where in light of the Picard-Lefschetz thimble approach, we split up the real-time path integral into two parts: the initial density matrix part which can be…
