27. Eye on ArXiv: 24 Apr 2008 - Detection of dark matter?
There was a lot of buzz recently (including the paper in New York Times) concerning the claim by DAMA/LIBRA team - they detected dark matter interactions with their detector at the level of 8 sigma
Their approach is the following: they try to find annual modulations in their DM signal (interaction of WIMPs with the material of their detector) due to fact that Earth is orbiting around the Sun. (…)
25. Geometry and causal structure of de Sitter space (Inflationary perturbations 4)
I discuss geometry, causal structure and behavior of QFT Green functions in de Sitter space
24. Inflation: description in terms of hydrodynamics (Inflationary perturbations 4)
This post continues my lecture notes on large scale structure, cosmological perturbations and inflation. The last post in this series was about the problem of initial conditions in FRW cosmology. (…)
23. Eye on ArXiv: 21 Apr 2008 - SUSY/non-SUSY duality
And so the new week began… Would be fun to finish another paper till Friday (the subject is “IR divergencies in de Sitter space”). (…)
