Inflation as an Information Bottleneck - A strategy for identifying universality classes and making robust predictions
Mafalda Dias, Jonathan Frazer, Alexander Westphal
In this work we propose a statistical approach to handling sources of theoretical uncertainty in string theory models of inflation. By viewing a model of inflation as a probabilist…
Primordial Gravitational Waves and the Swampland
Mafalda Dias, Jonathan Frazer, Ander Retolaza +1
The swampland conjectures seek to distinguish effective field theories which can be consistently embedded in a theory of quantum gravity from those which can not (and are hence ref…
Pole N-flation
Mafalda Dias, Jonathan Frazer, Ander Retolaza +2
A second order pole in the scalar kinetic term can lead to a class of inflation models with universal predictions referred to as pole inflation or -attractors. While this kineti…
Seven Lessons from Manyfield Inflation in Random Potentials
Mafalda Dias, Jonathan Frazer, M. C. David Marsh
We study inflation in models with many interacting fields subject to randomly generated scalar potentials. We use methods from non-equilibrium random matrix theory to construct the…
Numerical evaluation of the bispectrum in multiple field inflation
Mafalda Dias, Jonathan Frazer, David J. Mulryne +1
We present a complete framework for numerical calculation of the power spectrum and bispectrum in canonical inflation with an arbitrary number of light or heavy fields. Our method…
Simple emergent power spectra from complex inflationary physics
Mafalda Dias, Jonathan Frazer, M. C. David Marsh
We construct ensembles of random scalar potentials for interacting scalar fields using non-equilibrium random matrix theory, and use these to study the generation of observab…
