36. Eye on ArXiv: 6 May 2008 - Where does the cosmological perturbation theory actually break down?
I discuss the issue of cosmological perturbation theory breakdown and its relation to the regime of eternal inflation
34. Several questions about de Sitter
I ask several questions about Green’s functions on de Sitter
32. Eye on ArXiv: 30 Apr 2008 - Curvature perturbation from false vacuum inflation
Power spectrum of primordial perturbations is calculated for inlationary models with false minima of the inflaton potential.
30. Eye on ArXiv: 30 Apr 2008 - Effective QFT for inflation
Today, I think, the most interesting paper in ArXiv is the one by Steven Weinberg called “Effective field theory for inflation“. I would say, it generalizes results by Cheung et al. (…)
29. Eye on ArXiv: 28 Apr 2008 - D3/D7 brane inflation
I would like to briefly discuss the paper
Michael Haack, Renata Kallosh, Axel Krause, Andrei Linde, Dieter Lust, Marco Zagermann, “Update of D3/D7-Brane Inflation on K3 x T^2/Z_2″
released last friday. (…)
