Scalable quantum computation of Quantum Electrodynamics beyond one spatial dimension
Zong-Gang Mou, Bipasha Chakraborty
In the Hamiltonian formulation, Quantum Field Theory calculations scale exponentially with spatial volume, making real-time simulations intractable on classical computers and motiv…
Computing real-time quantum path integrals on Sewed, almost-Lefschetz thimbles
Zong-Gang Mou, Paul M. Saffin, Anders Tranberg
We present a method to compute real-time path integrals numerically, by Monte-Carlo sampling on near-Lefschetz thimbles. We present a collection of tools based on the Lefschetz thi…
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…
Dipole Radiation and Beyond from Axion Stars in Electromagnetic Fields
Mustafa A. Amin, Andrew J. Long, Zong-Gang Mou +1
We investigate the production of photons from coherently oscillating, spatially localized clumps of axionic fields (oscillons and axion stars) in the presence of external electroma…
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…
