Comment on "Viscous hydrodynamics relaxation time from AdS/CFT correspondence"
Makoto Natsuume, Takashi Okamura
This is a comment to hep-th/0703243. The paper determined the relaxation time tau_pi of the shear viscous stress for the N=4 SYM from AdS/CFT correspondence. The purpose of this co…

String theory and quark-gluon plasma
Makoto Natsuume
We review the AdS/CFT description of gauge theory plasmas for non-experts. We discuss the low shear viscosity, jet quenching, and J/psi-suppression, which are three major signature…

The singularity problem in string theory
Makoto Natsuume
We review the current status of the singularity problem in string theory for non-experts. After the problem is discussed from the point of view of supergravity, we discuss classic…
