Novel nonlocal gauge functions in electrodynamics and their effect on quantum mechanical phases
(2011)We point to previously overlooked solutions of the standard gauge transformation equations of Electrodynamics: the generalized "gauge functions" go beyond the usual Dirac phase factors (spatial or temporal integrals of ...

Worldline path integral for the massive Dirac propagator: A four-dimensional approach
(1999)We simplify and generalize an approach proposed by Di Vecchia and Ravndal to describe a massive Dirac particle in external vector and scalar fields. Two different path integral representations for the propagator are derived ...
