Note on the pragmatic mode-sum regularization method: translational-splitting in a cosmological background
Pau Beltrán-Palau, Adrián del Río, Sergi Nadal-Gisbert +1
The point-splitting renormalization method offers a prescription to calculate finite expectation values of quadratic operators constructed from quantum fields in a general curved s…
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…
