Phase Transitions in de Sitter: Quantum Corrections
José Eliel Camargo-Molina, Mariana Carrillo González, Arttu Rajantie
We investigate the decay rate of a false vacuum state in de Sitter space at high Hubble rates, using two methods: the Hawking-Moss instanton method which is fully quantum mechanica…
Phase transitions in de Sitter: The stochastic formalism
José Eliel Camargo-Molina, Arttu Rajantie
The stochastic spectral expansion method offers a simple framework for calculations in de Sitter spacetimes. We show how to extend its reach to metastable vacuum states, both in th…
Dark energy without fine tuning
José Eliel Camargo-Molina, Tommi Markkanen, Pat Scott
We present a two-field model that realises inflation and the observed density of dark energy today, whilst solving the fine-tuning problems inherent in quintessence models. One fie…
