QED Fermions in a noisy magnetic field background: The effective action approach
Jorge David Castaño-Yepes, Marcelo Loewe, Enrique Muñoz +1
We consider the effects of a noisy magnetic field background over the fermion propagator in QED, as an approximation to the spatial inhomogeneities and time-fluctuations that would…
QED Fermions in a noisy magnetic field background
Jorge David Castaño-Yepes, Marcelo Loewe, Enrique Muñoz +2
We consider the effects of a noisy magnetic field background over the fermion propagator in QED, as an approximation to the spatial inhomogeneities that would naturally arise in ce…
Path integral of the relativistic point particle in Minkowski space
Benjamin Koch, Enrique Muñoz
In this article, we analyze the fundamental global and local symmetries involved in the action for the free relativistic point particle. Moreover, we identify a hidden local symmet…
Gluon polarization tensor in a magnetized medium: Analytic approach starting from the sum over Landau levels
Alejandro Ayala, Jorge David Castaño-Yepes, M. Loewe +1
We present an analytic method to compute the one-loop magnetic correction to the gluon polarization tensor starting from the Landau-level representation of the quark propagator in…
A hidden constraint on the Hamiltonian formulation of relativistic worldlines
Benjamin Koch, Enrique Muñoz
Gauge theories with general covariance are particularly reluctant to quantization. We discuss the example of the Hamiltonian formulation of the relativistic point particle that, de…
The stepwise path integral of the relativistic point particle
Benjamin Koch, Enrique Muñoz
In this paper we present a stepwise construction of the path integral over relativistic orbits in Euclidean spacetime. It is shown that the apparent problems of this path integral,…
Symmetries of relativistic world-lines
Benjamin Koch, Enrique Muñoz, Ignacio Reyes
Symmetries are essential for a consistent formulation of many quantum systems. In this paper we discuss a previously unnoticed symmetry, which is present for any Lagrangian term th…
