Multi-particle quantum systems within the Worldline Monte Carlo formalism
Ivan Ahumada, Max Badcott, James P. Edwards +6
We extend the Worldline Monte Carlo approach to computationally simulating the Feynman path integral of non-relativistic multi-particle quantum-mechanical systems. We show how to g…
Worldline Modeling of Ultra-Intense Lasers for N-photon Scattering Processes
Ivan Ahumada, Patrick Copinger, James P. Edwards +1
The modeling of present and future ultra-intense lasers demands techniques that go beyond the standard diagrammatic approach to non-perturbatively fully capture the effects of stro…
Low-energy multi-photon scattering at tree-level and one-loop order in a homogeneous electromagnetic field
Ivan Ahumada, Patrick Copinger, James P. Edwards
We study low energy photons coupled to scalar and spinor matter in the presence of an arbitrary homogeneous electromagnetic field in a first-quantised (worldline) approach. Utilisi…
Monte Carlo generation of localised particle trajectories
Ivan Ahumada, James P. Edwards
We introduce modifications to Monte Carlo simulations of the Feynman path integral that improve sampling of localised interactions. The new algorithms generate trajectories in simp…
