Quantum field theory
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.
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
35. Lectures on AdS/CFT by Maldacena
Lectures on AdS/CFT by Juan Maldacena
34. Several questions about de Sitter
I ask several questions about Green’s functions on de Sitter
33. Schwinger-Keldysh: information carried by Keldysh Green’s functions (nonequilibrium diagrammatic methods 1)
I discuss information carried by Keldysh Green’s functions in the non-equilibrium quantum field theory.
