Secular effects of Ultralight Dark Matter on Binary Pulsars
Diego Blas, Diana López Nacir, Sergey Sibiryakov
Dark matter (DM) can consist of very light bosons behaving as a classical scalar field that experiences coherent oscillations. The presence of this DM field would perturb the dynam…
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…
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…
