Paper published in Physical Review D

Thu, 08 Mar 2012 15:50:33 +0100

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 during inflationary expansion with more than one field. We performed numerical simulations using Pyflation version 0.

New paper and Pyflation software package

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 range of potentials to be analysed. The paper is called “Second Order Perturbations During Inflation Beyond Slow-roll” and already has a record on SPIRES and Inspire Beta.

Checklist for arXiv submission

Fri, 04 Mar 2011 12:47:08 +0100

I am currently finishing up a paper that is about to be submitted to the arXiv and I thought I would go through the list of things I normally do just before sending the work off. It’s mainly a common sense list but in the rush to get something out it is good to have a list to work from to make sure you don’t miss anything (misspelling collaborators names is not helpful!).

Check bib style is correct. If the journal you are planning to submit to has a particular house style for the bibliography it is probably worth using it in the arXiv submission.
Check bibliography text is correct. Even though I think BiBTeX is the great, and much easier than preparing the bibliography by hand (which some people still do), there can be instances when a stray space or mistakenly capitalised letter appear. If you get your BiBTeX entries from SPIRES or Inspire this is mostly taken care of, but there is always the odd paper or book entry that you have typed in by hand. Check the final output in the paper, not just the .bib file contents.
