A second-order stochastic effective theory for the long-distance behaviour of scalar fields in de Sitter spacetime
Archie Cable
This thesis introduces an effective theory for the long-distance behaviour of scalar fields in de Sitter spacetime, known as the second-order stochastic theory, with the aim of com…
Stochastic parameters for scalar fields in de Sitter spacetime
Archie Cable, Arttu Rajantie
The stochastic effective theory approach, often called stochastic inflation, is widely used in cosmology to describe scalar field dynamics during inflation. The existing formulatio…
Spectators no more! How even unimportant fields can ruin your Primordial Black Hole model
Ashley Wilkins, Archie Cable
In this work we terminate inflation during a phase of Constant Roll by means of a waterfall field coupled to the inflaton and a spectator field. The presence of a spectator field m…
Second-order stochastic theory for self-interacting scalar fields in de Sitter spacetime
Archie Cable, Arttu Rajantie
We introduce a second-order stochastic effective theory for light scalar fields in de Sitter spacetime, extending the validity of the stochastic approach beyond the massless limit…
Free scalar correlators in de Sitter via the stochastic approach beyond slow roll
Archie Cable, Arttu Rajantie
The stochastic approach to calculating scalar correlation functions in de Sitter spacetime is extended beyond the overdamped "slow roll" approximation. We show that with the correc…
