168. Yoneya on gravity from strings
As you may remember, recently we’ve discussed the paper by Alexander Polyakov - essentially, his contribution into the forthcoming volume “The birth of string theory”. (…)
166. Multifield Inflation with a Random Potential (I)
This is a guest blog post by Jiajun Xu from Cornell. Dmitry.
This is a guest post by Dmitry’s invitation. (…)
163. What is AdS/QCD?
This is a a guest post by Josh Erlich from the College of William and Mary, Williamsburg. Dmitry. (…)
156. Again about condensed matter applications of AdS-CFT
Peter Horava has recently released a somewhat mysterious paper about non-relativistic Yang-Mills theories. (…)
155. Witten explains how to quantize gauge theory
Long time (almost 6 months?) ago Peter Woit wrote about Yau Birthday Conference and briefly mentioned the talk Edward Witten gave there. (…)
154. Solutions to problems from Polchinski, String theory
A rather incredible paper was recently published in ArXiv - Matthew Headrick decided to solve all problems in both volumes of Joe Polchinski’s “String theory” (well, not quite, actually about 80 problems out of 200 ) and publish them as a paper. (…)
152. Volume of the Universe after inflation
Back to work after a way too short Xmas break Since we were recently a bit into black hole complementarity and information loss paradox, maybe it is also worth discussing a bit the physics of de Sitter space. (…)
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. (…)
148. On surface growth
As Barabasi and Stanley state in the book “Fractal concepts of surface growth“,
most of our life takes place on the surface of something. (…)
145. Quantum and thermal decay in de Sitter space
Yesterday there was an interesting talk at Perimeter Institute - Adam Brown from Columbia University has discussed vacuum decay in de Sitter space. (…)
144. For lazy, yet curious students
Suppose you are a cosmologist - a postdoc or an assistant professor. (…)
143. The structure of correlation functions in single-field inflation
This is a guest post by Sarah Shandera from the University of Columbia. Dmitry. (…)
142. Chaotic inflation on the landscape?
By a chance, do you remember the paper by Nemanja Kaloper and Lorenzo Sorbo that we have recently discussed? (…)
141. On information loss paradox, statistical and quantum mechanics
Recently, I got into the discussion of information loss paradox in spacetimes with timelike and spacelike horizons (that is, black holes, de Sitter and staff like them). (…)
140. First two weeks of December at NEQNET
Dear friends
Before I proceed to the (becoming usual already) list of posts published at NEQNET during the last two weeks, let me say a couple of words about the blog itself, which is currently the source of my pride
1. (…)
