47. Planck 2008: First and second days
First and second days of the PLANCK 2008 conference: flavor physics, RS phenomenology, WMAP, bigravity, WIMPonium, black holes and number of species.
45. Quantization of cosmological perturbations. Mukhanov-Sasaki variable (Inflationary perturbations 5)
I introduce Mukhanov-Sasaki variable, show how to quantize inflationary perturbations and again calculate the power spectrum of primordial perturbations - by QFT this time.
44. Cosmological perturbations in the presence of scalar field (Inflationary perturbations 5)
I discuss cosmological perturbation theory in the Universe where the dominant component of matter is a scalar field. It is show that spectrum of inflationary perturbations is nearly flat.
40. Inflation: field-theoretic description (Inflationary perturbations 4)
I discuss simplest field theoretic models of inflation, dynamics of inflation at the level of background and Hamilton-Jacobi formalism for inflation.
38. And again about effective QFT for inflation
I show that effective QFT corrections to correlator of Mukhanov variable found by Armedariz-Picon et al. are due to effects of eternal inflation.
