Non-Minimally Coupled Chain Inflation at High Scales

Miguel Barroso Varela, Orfeu Bertolami, Katherine Freese +1

Chain inflation offers an alternative to standard slow-roll dynamics, with accelerated expansion proceeding through a sequence of rapid quantum tunneling events between metastable…

Gravitational Wave Echoes of the First Order Phase Transition in a Kination-Induced Big Bang

Richard Casey, Katherine Freese, Evangelos I. Sfakianakis

Gravitational waves (GWs) produced during first-order phase transitions (FOPTs) in the early universe provide a powerful probe of nonstandard cosmological histories. We study GW pr…
