Primordial Black Holes from Kinetic Preheating
Peter Adshead, Eve Currens, John T. Giblin
We demonstrate that violent kinetic preheating following inflation can lead to the formation of black holes in the early Universe. In -attractor models with derivative inflaton…
Twisting inflation to sub-Planckian axion decay constants
Peter Adshead, Suddhasattwa Brahma, Indranil Das
We study pseudoscalar inflation in the Einstein-Cartan-Palatini (first-order) formulation of gravity while allowing for torsion. We introduce two non-minimal interactions in the gr…
Gravitational Waves from Kinetic Preheating
Peter Adshead, John T. Giblin, Avery Tishue
We study gravitational wave production during kinetic preheating after inflation with a focus on scenarios that arise in -attractor models where a scalar dilaton-like inflaton i…
Mechanical cosmology: simulating scalar fluctuations in expanding Universes using synthetic mechanical lattices
Brendan Rhyno, Ivan Velkovsky, Peter Adshead +2
Inspired by recent advances in observational astrophysics and continued explorations in the field of analog gravity, we discuss the prospect of simulating models of cosmology withi…
Kinetic Preheating after -attractor Inflation
Peter Adshead, John T. Giblin, Reid Pfaltzgraff-Carlson
We study preheating via kinetic couplings after dilaton-axion -attractor inflation. We focus on E-model -attractor driven inflation where the inflaton is kinetically coupled…
Gauge preheating with full general relativity
Peter Adshead, John T. Giblin, Ryn Grutkoski +1
We study gauge preheating following pseudoscalar-driven inflation in full general relativity. We implement the Baumgarte-Shapiro-Shibata-Nakamura (BSSN) scheme to solve the full no…
