Running couplings from adiabatic regularization
Antonio Ferreiro, Jose Navarro-Salas
We extend the adiabatic regularization method by introducing an arbitrary mass scale in the construction of the subtraction terms. This allows us to obtain, in a very robust wa…
Role of gravity in the pair creation induced by electric fields
Antonio Ferreiro, Jose Navarro-Salas, Silvia Pla
We analyze the pair production induced by homogenous, time-dependent electric fields in an expanding space-time background. We point out that, in obtaining the semiclassical Maxwel…
Adiabatic expansions for Dirac fields, renormalization, and anomalies
J. Fernando Barbero G., Antonio Ferreiro, Jose Navarro-Salas +1
We introduce an iterative method to univocally determine the adiabatic expansion of the modes of Dirac fields in spatially homogeneous external backgrounds. We overcome the ambigui…
Pair creation in electric fields, anomalies, and renormalization of the electric current
Antonio Ferreiro, Jose Navarro-Salas
We investigate the Schwinger pair production phenomena in spatially homogeneous strong electric fields. We first consider scalar QED in four-dimensions and discuss the potential am…
