58. Stability of de Sitter space: dS as a perfect interferometer
Let us now show that QFT of a massive scalar field in de Sitter space features instabilities if the number of dimensions is odd. (…)
53. Eternal inflation: stochastic approach 1 (Inflationary perturbations 7)
In this post I start to discuss physics of eternal inflation - regime where superhorizon cosmological perturbations become of the order 1.
13. Eye on ArXiv: 7 Apr 2008 - Gravity cutoff in theories with large descrete symmetries
Gia Dvali, Michele Redi, Sergey Sibiryakov, Arkady Vainshtein, “Gravity Cutoff in Theories with Large Discrete Symmetries”
It is a development of one year old extremely elegant Dvali’s idea that the possible maximal number of species is bounded by the gravitational physics. (…)
