Constant-Roll Inflation (2504.16757v1)
Published 23 Apr 2025 in astro-ph.CO, gr-qc, and hep-th
Abstract: Constant-roll inflation is a distinctive class of phenomenological inflationary models in which the inflaton's rate of roll remains constant. It provides an exact solution that is compatible with the latest observational constraints and offers a natural framework for enhancing the curvature power spectrum, which is relevant to the formation of primordial black holes. In this paper, I review constant-roll inflation in memory of Alexei Starobinsky.
