Trans-Planckian Issues for Inflationary Cosmology
Robert Brandenberger, Jerome Martin
The accelerated expansion of space during the period of cosmological inflation leads to trans-Planckian issues which need to be addressed. Most importantly, the physical wavelength…
Ultra Slow-Roll Inflation and the non-Gaussianity Consistency Relation
Jerome Martin, Hayato Motohashi, Teruaki Suyama
Ultra slow-roll inflation has recently been used to challenge the non-Gaussianity consistency relation. We show that this inflationary scenario belongs to a one parameter class of…
The Quantum State of Inflationary Perturbations
Jerome Martin
This article reviews the properties of the quantum state of inflationary perturbations. After a brief description of the inflationary background, the wavefunction of the Mukhanov-S…
The scalar bi-spectrum during preheating in single field inflationary models
Dhiraj Kumar Hazra, Jerome Martin, L. Sriramkumar
In single field inflationary models, preheating refers to the phase that immediately follows inflation, but precedes the epoch of reheating. During this phase, the inflaton typical…
Cosmological Inflation and the Quantum Measurement Problem
Jerome Martin, Vincent Vennin, Patrick Peter
According to cosmological inflation, the inhomogeneities in our universe are of quantum mechanical origin. This scenario is phenomenologically very appealing as it solves the puzzl…
Everything You Always Wanted To Know About The Cosmological Constant Problem (But Were Afraid To Ask)
Jerome Martin
This article aims at discussing the cosmological constant problem at a pedagogical but fully technical level. We review how the vacuum energy can be regularized in flat and curved…
