PyTransport: A Python package for the calculation of inflationary correlation functions
David J. Mulryne, John W. Ronayne
PyTransport constitutes a straightforward code written in C++ together with Python scripts which automatically edit, compile and run the C++ code as a Python module. It has been wr…
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…
Linear Density Perturbations in Multifield Coupled Quintessence
Alexander Leithes, Karim A. Malik, David J. Mulryne +1
We study the behaviour of linear perturbations in multifield coupled quintessence models. Using gauge invariant linear cosmological perturbation theory we provide the full set of g…
Non-Gaussianity in multiple three-form field inflation
K. Sravan Kumar, David J. Mulryne, Nelson J. Nunes +2
In this work, we present a method for implementing the formalism to study the primordial non-Gaussianity produced in multiple three-form field inflation. Using a dual descript…
