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. https://www.ianhuston.net/2010/03/relativity-cosmology-seminar/ Thu, 25 Mar 2010 14:39:08 +0100 https://www.ianhuston.net/2010/03/relativity-cosmology-seminar/ Yesterday I gave my first seminar as a postdoc in the regular Relativity and Cosmology series at QMUL. People seemed to engage with the material and there were quite a few questions at the end. The slides for the talk are available as a pdf or through the embedded widget below. My style for talks is heavily skewed towards minimalist slides with lots of verbal explanation so without having me beside you to guide you through them they might be hard to understand.
