366. Some interesting recent papers in Arxiv
Just wanted to acknowledge their existence, although I’ll not be really able to review them due to the lack of time…
1. Quantum field theory
1.1. “Non-Abelian Duality and Confinement in N=2 Supersymmetric QCD” by Michail Shifman and Alesha Yung. The authors study transitions from weak to strong coupling in N = 2 SQCD that happen when you change parameters of the theory – that is, the coefficient 
in front of Fayet?Iliopoulos term and quark mass differences. Here the authors are interested in the case 
and study phases of the theory at different values of .

365. Inertial confinement – using lasers for compression
I hope you are not getting bored too much by my discussion of thermonuclear fusion in inertial confinement reactors, because today I’m going to continue 
and finally start explaining why do they want to use lasers in HiPER to compress plasma.

364. Thermonuclear reactors. More on inertial confinement
Last time I did not quite finish with the discussion of physics of inertial confinement, so let me continue…
An important parameter that characterizes plasma in reactors with inertial confinement is the ratio between the geometric size 
of the region where reactions take place and the mean free path 
of 
-particles. It basically determines the ability of thermonuclear reactions in the plasma to self-sustain – if particles are adsorbed faster, plasma is getting warmed up more effectively. In other words, one naturally would want to increase or decrease . How to do that?

362. Kepler sees first light
Star cluster NGC6791 from the Kepler’s first light image
Just a small part of Kepler’s field of view. The star in the center of the field is known to have large Jupiter-like planet called TrES-2.

361. NEQNET: first two weeks of April
Well, it seems that other two weeks have passed… What’s up? First of all, it looks like I figured out why energy seems to dissipate inhomogeneously in a turbulent flow with very large Reynolds numbers (kindly see the list N4 below). Apart from this topic, other things that I was interested in during these two weeks are listed here:
