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). (…)
65. Simulations of decaying turbulence
A group of people (with Jonathan Dursi being the only one I know personally among them) has written nice review of existing software for stimulating decaying compressible (supersonic) turbulence with the goal to compare performance of the codes. (…)
59. Eye on Arxiv: Quantum corrections to eta/s
I decided to turn the de Sitter discussion off for a moment, it would be more appropriate to return to it after the paper is ready anyway Hopefully, it will not take too much time for you to see it in ArXives. (…)
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. (…)
57. Stability of de Sitter space: statement of the problem 1
Ok, friends, I feel that the time has come to let you know about things I am currently involved in – namely, understanding of intrinsic stability of the de Sitter space. (…)
