Spin in the Worldline Path Integral in 2+1 Dimensions
C. D. Fosco, J. Sanchez-Guillen, R. A. Vazquez
We construct a worldline path integral for the effective action and propagator of a Dirac field in 2+1 dimensions in an Abelian gauge field background. Integrating over an auxiliar…

New tests and applications of the worldline path integral in the first order formalism
C. D. Fosco, J. Sanchez-Guillen, R. A. Vazquez
We present different non-perturbative calculations within the context of Migdal's representation for the propagator and effective action of quantum particles. We first calculate th…

Zero modes in non local domain walls
C. D. Fosco, G. Torroba
We generalize the Callan-Harvey mechanism to the case of actions with a non local mass term for the fermions. Using a 2+1-dimensional model as a concrete example, we show that both…
