Particle creation and the Schwinger model
José Navarro-Salas, Silvia Pla
We study the particle creation process in the Schwinger model coupled with an external classical source. One can approach the problem by taking advantage that the full quantized mo…
New partial resummation of the QED effective action
Silvia Pla, Jose Navarro-Salas
We explain a conjecture which states that the proper-time series expansion of the one-loop effective Lagrangian of quantum electrodynamics can be partially summed in all terms cont…
-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…
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…
Translational anomaly of chiral fermions in two dimensions
Pau Beltrán-Palau, Jose Navarro-Salas, Silvia Pla
It is well known that a quantized two-dimensional Weyl fermion coupled to gravity spoils general covariance and breaks the covariant conservation of the energy-momentum tensor. In…
Breaking of adiabatic invariance in the creation of particles by electromagnetic fields
Pau Beltrán-Palau, Antonio Ferreiro, Jose Navarro-Salas +1
Particles are spontaneously created from the vacuum by time-varying gravitational or electromagnetic backgrounds. It has been proven that the particle number operator in an expandi…
