16. Eye on ArXiv: 10 Apr 2008 - NG in ekpyrotic models, quantum noise as entanglement meter
Ekpyrotic scenario predicts much higher level of primordial non-gaussianity than single field inflationary scenarios.
15. Anderson localization. Just crossed my mind…
I personally consider Anderson localization as one of the most prominent dynamic vacuum selection principles on the string theory landscape. Let me remind you the main idea behind it. (…)
14. Eye on ArXiv: 8 Apr 2008 - Unifying inflation, dark matter and dark energy?
1. Andrew R. Liddle, Cedric Pahud, L. Arturo Urena-Lopez, “Triple unification of inflation, dark matter, and dark energy using a single field”. (…)
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. (…)
