After a lot of work, “Large trispectrum in two-field slow-roll inflation” was released on the arXiv yesterday as arXiv:1203.6844. In this article Joe Elliston, Laila Alabidi, David Mulryne, Reza Tavakol and I look at the generation of higher order statistics during inflation in the early universe. In the early universe the curvature perturbations, which later [...]

Paper published in Physical Review D
My latest paper “Calculating nonadiabatic pressure perturbations during multifield inflation”, written with Adam Christopherson, has now been published in Physical Review D as Phys. Rev. D 85, 063507. The DOI is 10.1103/PhysRevD.85.063507 and if you want to get the (freely available) arXiv version the number is arXiv:1111.6919. This paper investigates the isocurvature or nonadiabatic perturbations [...]
Two new papers on the arXiv
Last Tuesday was a bit hectic for me as I tried to coordinate the last minute changes needed to put two papers on the arXiv servers for the next day. 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: [...]
Big Bang Fair 2011
As part of my outreach activities this year I participated in the speed networking sessions of the Big Bang Fair held last week in East London’s ExCeL centre. I had a great time at the previous London based Big Bang Fair in 2009 and since then the event has only got bigger, louder and more [...]
