The two articles which are now available are numbered 1111.6919 and 1111.6940: Calculating Non-adiabatic Pressure Perturbations during Multi-field Inflation Ian Huston, Adam J. Christopherson Abstract: [...]

New paper and Pyflation software package

By Ian | Published: March 7, 2011

My latest paper has just hit the arXiv and is now available. The paper builds on the numerical work I previously completed on cosmological perturbations beyond linear order. The new results do not assume slow-roll in the calculation of the source term for the second order equations of motion and so allow a much greater [...]

There were lots of very interesting talks, and I hope to give a flavour of some of the issues that were mentioned over the course of the meeting. The list of participants and the programme [...]

Thesis now online

By Ian | Published: July 6, 2010

I passed my viva examination a few months ago, and after very helpful suggestions from my two examiners I submitted the final version of my PhD thesis to the QMUL authorities a month ago. The paperwork all went through so I have now completely finished my doctoral training. All that remains to be done is [...]
