We extend the `moment transport method' for calculating the statistics of inflationary perturbations to the quantum phase of evolution on sub-horizon scales. The quantum transport equations form a set of coupled ordinary differential equations for the evolution of quantum correlation functions during inflation, which are valid on sub- and super-horizon scales, and reduce to the known classical transport equations after horizon crossing. The classical and quantum equations follow directly from… 
Computing observables in curved multifield models of inflation - A guide (with code) to the transport method
The transport method is efficient and encompasses scenarios with curved field-space metrics, violations of slow-roll conditions and turns of the trajectory in field space, including massive modes and models with quasi-single-field dynamics.
Non-linear effects in early Universe cosmology
In this thesis, we discuss several instances in which non-linear behaviour affects cosmological evolution in the early Universe. We begin by reviewing the standard cosmological model and the tools
Primordial fluctuations and non-Gaussianities in sidetracked inflation
Heavy scalar fields can undergo an instability during inflation as a result of their kinetic couplings with the inflaton. This is known as the geometrical destabilization of inflation, as it relies
Numerical evaluation of the bispectrum in multiple field inflation
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 includes all
Multifield consequences for D-brane inflation
We analyse the multifield behaviour in D-brane inflation when contributions from the bulk are taken into account. For this purpose, we study a large number of realisations of the potential; we find
Slow-roll corrections in multi-field inflation: a separate universes approach
In view of cosmological parameters being measured to ever higher precision, theoretical predictions must also be computed to an equally high level of precision. In this work we investigate the impact
Calculation of the Curvature Perturbation During Non-Canonical Multifield Inflation
In this thesis we study models of inflation with a curved field-space metric. We concern ourselves with the calculation of the statistics of curvature perturbations which is essential for connecting
Manyfield Inflation in Random Potentials
We construct models of inflation with many randomly interacting fields and use these to study the generation of cosmological observables. We model the potentials as multi-dimensional Gaussian random
Novel techniques for calculating inflationary observables
Comparing the predictions from different inflation models to observations of the Cosmic Microwave Background (CMB) and the Large-Scale Structure (LSS) is a non-trivial task. One needs to calculate
Observable predictions of generalised inflationary scenarios
Inflation is an early period of accelerated cosmic expansion, thought to be sourced by high energy physics. A key task today is to use the influx of increasingly precise observational data to


Primordial non-Gaussianities from multiple-field inflation
We calculate the three-point correlation function evaluated at horizon crossing for a set of interacting scalar fields coupled to gravity during inflation. This provides the initial condition for the
The δN formula is the dynamical renormalization group
We derive the `separate universe' method for the inflationary bispectrum, beginning directly from a field-theory calculation. We work to tree-level in quantum effects but to all orders in the
We study the evolution of non-Gaussianity in multiple-field inflationary models, focusing on three fundamental questions: (a) How is the sign and peak magnitude of the non-linearity parameter fNL
Moment transport equations for non-Gaussianity
A novel method for calculating the primordial non-Gaussianity produced by super-horizon evolution during inflation using a transport equation and expresses expressions in a field-space covariant form which are valid for any number of fields.
Primordial non-Gaussianities in single-field inflation
We calculate the three-point function for primordial scalar fluctuations in a single-field inflationary scenario where the scalar field Lagrangian is a completely general function of the field and
Non-Gaussianity of inflationary field perturbations from the field equation
We calculate the tree-level bispectrum of the inflaton field perturbation directly from the field equations, and construct the corresponding fNL parameter. Our results agree with previous ones
Inflationary perturbation theory is geometrical optics in phase space
A pressing problem in comparing inflationary models with observation is the accurate calculation of correlation functions. One approach is to evolve them using ordinary differential equations
Primordial Non-Gaussianity in Multi-Scalar Inflation
We give a concise formula for the non-Gaussianity of the primordial curvature perturbation generated on super-horizon scales in multi-scalar inflation model without assuming slow-roll conditions.
Moment transport equations for the primordial curvature perturbation
In a recent publication, we proposed that inflationary perturbation theory can be reformulated in terms of a probability transport equation, whose moments determine the correlation properties of the
Multi-field inflation with random potentials: field dimension, feature scale and non-Gaussianity
We explore the super-horizon evolution of the two-point and three-point correlation functions of the primordial density perturbation in randomly-generated multi-field potentials. We use the Transport
