149. Towers of vacua in SUSY field theories
Reading the previous post about dynamical RG treatment of the fractal surface growth problem some of you may have recalled that several months ago we (me, Niko Jokela and Jaydeep Majumder) have used dynamical RG methods to describe behavior of eternal inflation on a nearly continuous landscape. (…)
110. Introducing doubt in Bayesian statistics 1
This is a guest post by my old friend Pascal Vaudrevange, who was a student of Lev Kofman when we were together in CITA, and is now a postdoc at Case Western University working with Glenn Starkman. (…)

* Quintessence on the string theory landscape? (…)
96. Quintessence with w less than -1
In another very interesting recent paper on quintessence the Italian Team (Creminelli, D’Amico, Norena, Vernizzi - and warmest regards from Helsinki if you read it, Filippo :-)) is trying to construct an reliable example of QFT that behaves like the quintessence with ?ghost-like? (…)
83. Quintessence on the string theory landscape?
Nemanja Kaloper and Lorenzo Sorbo have recently released a paper explaining how the quintessence can be realized on string theory landscape. What is quintessence and why the question is important? (…)
69. Happy Halloween!
Since it is Halloween, today’s story is about ghosts…
Let us follow the analysis of massive gravity theory in de Sitter background by Izumi and Tanaka. (…)
66. Some interesting talks worth watching
Steve Carlip talks about topologically massive gravity at Perimeter, namely, about 3d topologically massive gravity in AdS and finds that it is unstable (even for chiral values Strominger mentioned at Strings 08). (…)
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). (…)
