Quantum mechanical path integrals in the first quantised approach to quantum field theory
James P. Edwards, Christian Schubert
Perturbative quantum field theory usually uses second quantisation and Feynman diagrams. The worldline formalism provides an alternative approach based on first quantised particle…
Worldline formalism for a confined scalar field
Olindo Corradini, James P. Edwards, Idrish Huet +2
The worldline formalism is a useful scheme in quantum field theory which has also become a powerful tool for numerical computations. The key ingredient in this formalism is the fir…
Applications of the worldline Monte Carlo formalism in quantum mechanics
James P. Edwards, Urs Gerber, Christian Schubert +3
In recent years efficient algorithms have been developed for the numerical computation of relativistic single-particle path integrals in quantum field theory. Here, we adapt this "…
Massless Rarita-Schwinger field from a divergenceless anti-symmetric-tensor spinor of pure spin-
James P. Edwards, Mariana Kirchbach
We construct the Rarita-Schwinger basis vectors, , spanning the direct product space, , of a massless four-vector, , with massless Majorana spinors,…
Reducible contributions to quantum electrodynamics in external fields
Naser Ahmadiniaz, James P. Edwards, Anton Ilderton
We consider one-particle reducible (1PR) contributions to QED and scalar QED processes in external fields, at one-loop and two-loop order. We investigate three cases in detail: con…
