New counterterms induced by trans-Planckian physics in semiclassical gravity
Diana López Nacir, Francisco D. Mazzitelli
We consider free and self-interacting quantum scalar fields satisfying modified dispersion relations in the framework of Einstein-Aether theory. Using adiabatic regularization, we…
Decoherence induced by Smith-Purcell radiation
Ezequiel Alvarez, Francisco D. Mazzitelli
The interaction between charged particles and the vacuum fluctuations of the electromagnetic field induces decoherence, and therefore affects the contrast of fringes in an interfer…
Backreaction in trans-Planckian cosmology: renormalization, trace anomaly and selfconsistent solutions
Diana López Nacir, Francisco D. Mazzitelli
We analyze the semiclassical Einstein equations for quantum scalar fields satisfying modified dispersion relations. We first discuss in detail the renormalization procedure based o…
Quantum dissipative effects in moving mirrors: a functional approach
C. D. Fosco, F. C. Lombardo, F. D. Mazzitelli
We use a functional approach to study various aspects of the quantum effective dynamics of moving, planar, dispersive mirrors, coupled to scalar or Dirac fields, in different numbe…
Adiabatic renormalization in theories with modified dispersion relations
D. Lopez Nacir, F. D. Mazzitelli, C. Simeone
We generalize the adiabatic renormalization to theories with dispersion relations modified at energies higher than a new scale . We obtain explicit expressions for the mean va…
