The paperwork all went through so I have now completely finished my doctoral training. All that remains to be done is the celebratory donning of a floppy cloth cap and scarlet robes at the graduation ceremony in a few weeks. https://www.ianhuston.net/2009/07/numerical-calculation-of-second-order-perturbations/ Thu, 23 Jul 2009 16:30:43 +0100 https://www.ianhuston.net/2009/07/numerical-calculation-of-second-order-perturbations/ My new paper, written with Karim Malik, has just been released into the wild. We show that it is possible to numerically simulate second order perturbations for a single scalar field with a canonical action. I’ve been working on this for a long time and learned a lot about the mechanics of inflation in the process. I’ve also churned out quite a lot of python code, and learned some rudimentary parallel programming. https://www.ianhuston.net/2008/07/gradschool-graduate/ Mon, 28 Jul 2008 16:54:32 +0100 https://www.ianhuston.net/2008/07/gradschool-graduate/ As a graduate student any time taken away from the main task at hand, getting a PhD, can seem like a wasted opportunity. Especially when the time is not actually for a resting holiday in the sun, but is focussed on those hard-to-define transferable skills we are all told to cherish. So, it may come as something of a shock to learn that I have just spent some such time away from my work, honing those tenuous skills, and have come back re-energized and full of enthusiasm.
