-summed form of the QED effective action
Jose Navarro-Salas, Silvia Pla
We conjecture that the proper-time series expansion of the one-loop effective Lagrangian of quantum electrodynamics can be summed in all terms containing the field-strength invaria…
Pair production due to an electric field in 1+1 dimensions and the validity of the semiclassical approximation
Silvia Pla, Ian M. Newsome, Robert S. Link +2
Solutions to the backreaction equation in 1+1-dimensional semiclassical electrodynamics are obtained and analyzed when considering a time-varying homogeneous electric field initial…
R-summed form of adiabatic expansions in curved spacetime
Antonio Ferreiro, Jose Navarro-Salas, Silvia Pla
The Feynman propagator in curved spacetime admits an asymptotic (Schwinger-DeWitt) series expansion in derivatives of the metric. Remarkably, all terms in the series containing the…
Adiabatic regularization for Dirac fields in time-varying electric backgrounds
Pau Beltrán-Palau, Jose Navarro-Salas, Silvia Pla
The adiabatic regularization method was originally proposed by Parker and Fulling to renormalize the energy-momentum tensor of scalar fields in expanding universes. It can be exten…
