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: Isocurvature perturbations naturally occur in models of inflation consisting of more than one scalar field. https://www.ianhuston.net/2011/03/new-paper-and-pyflation-software-package/ Mon, 07 Mar 2011 12:31:02 +0100 https://www.ianhuston.net/2011/03/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.
