Photoemission with Chemical Potential from QCD Gravity Dual
Andrei Parnachev, David A. Sahakyan
We consider a brane construction which gives rise to a large N QCD at sufficiently small energies. Using the gravity dual of this system, we study chiral phase tran…
Chiral Phase Transition from String Theory
Andrei Parnachev, David A. Sahakyan
The low energy dynamics of a certain D-brane configuration in string theory is described at weak t'Hooft coupling by a non-local version of the Nambu-Jona-Lasinio model. We study t…
On the Connection between N=2 Minimal String and (1,n) Bosonic Minimal String
David A. Sahakyan, Tadashi Takayanagi
We study the scattering amplitudes in the N=2 minimal string or equivalently in the N=4 topological string on ALE spaces. We find an interesting connection between the tree level a…
On Non-Critical Superstring/Black Hole Transition
Andrei Parnachev, David A. Sahakyan
An interesting case of string/black hole transition occurs in two-dimensional non-critical string theory dressed with a compact CFT. In these models the high energy densities of st…
The Ground Ring of N=2 Minimal String Theory
Anatoly Konechny, Andrei Parnachev, David A. Sahakyan
We study the $\NN=2$ string theory or the $\NN=4$ topological string on the deformed CHS background. That is, we consider the $\NN=2$ minimal model coupled to the $\NN=2$ Liouville…
Comments on D-brane Dynamics Near NS5-Branes
David A. Sahakyan
We study the properties of a D-brane in the presence of NS5 branes. The Dirac-Born-Infeld action describing the dynamics of this D-brane is very similar to that of a non-BPS D-…
