Quantum field theory
22. About decoherence in quasi de Sitter space
My discussion of disorder on the landscape with Lubos continues (L - Lubos, D - me). (…)
21. About probabilities in cosmology (and general) and in stochastic inflation in particular
Discussion was initiated by the question “what is the physical meaning of time 
in vacuum dynamics equations” that was smoothly transformed into the question “what is the meaning of probability 
in the vacuum dynamics equations”. My answer was that is the world time for the 4-dim observer and is the probability for him to measure a given value of the cosmological constant. Lubos replied:
19. Disorder on the landscape: non-technical intro
Today I will kindly allow myself a bit of selfpromotion As I said yesterday, our paper “Disorder on the landscape” is finally out (by the way, Lubos Motl already has a very nice post about it on his blog). (…)
18. Eye on ArXiv: 15 Apr 2008 - Transplanckian physics, brane cosmology and holographic mesons
Sorry for being quiet for so long. The reason is we were finising a paper, asked for comments and got a lot of them. The paper is finally submitted to appear on ArXiv in tomorrow’s listings. (…)
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. (…)
12. Eye on ArXiv: 4 Apr 2008 - KS throat cloaking, non-gaussianity and Mathur’s fuzzballs
1. Alex Buchel, Lev Kofman “Black Universe epoch in string cosmology”
Alex and Lev write about multithroat scenario in string cosmology. (…)
