Macroscopic strings as heavy quarks in large N gauge theory and Antide Sitter supergravity
 PHYS. J. C22
"... Maldacena has put forward large N correspondence between superconformal field theories on the brane and antide Sitter supergravity in spacetime. We study some aspects of the correspondence between N = 4 superconformal gauge theory on D3brane and maximal supergravity on adS5 × S5 by introducing mac ..."

potential and again find agreements between the gauge theory and the supergravity results. By turning on RamondRamond zeroform potential, we also study θ vacuum angle dependence of the static potential. We finally discuss dynamical realization of loop equation via turning on local electric field
Holography with RamondRamond fluxes
, 2002
"... Starting from the nonlinear sigma model of the IIB string in the lightcone gauge, we analyze the role of RR fluxes in Holography. We find that the worldsheet theory of states with only left or right moving modes does not see the presence of RR fields threading a geometry. We use this significant s ..."

Starting from the nonlinear sigma model of the IIB string in the lightcone gauge, we analyze the role of RR fluxes in Holography. We find that the worldsheet theory of states with only left or right moving modes does not see the presence of RR fields threading a geometry. We use this significant simplification to compute part of the strong coupling spectrum of the two dimensional NCOS theory. We also reproduce the action of a closed string in a PPwave background using this general formalism; and we argue for various strategies to find new systems where the closed string theory may be exactly solvable. 1
Tduality in RamondRamond backgrounds

"... Using the pure spinor formalism on the worldsheet, we derive the Tduality rules for all target space couplings in an efficient manner. The worldsheet path integral derivation is a proof of the equivalence of the Tdual RamondRamond backgrounds which is valid nonperturbatively in the string leng ..."

RamondRamond fields and Ktheory
 JHEP 0005 (2000), 032, also at hepth/9912279. TOPOLOGICAL TDUALITY AND KKMONOPOLES
"... Abstract: Just as Dbrane charge of typeIIA and typeIIB superstrings is classi ed, respectively, by K1(X) and K(X), RamondRamond elds in these theories are classied, respectively, by K(X) and K1(X). By analyzing a recent proposal for how to interpret quantum selfduality of RR elds, we show that ..."

We use the recently found matrix description of noncritical superstring theory of Type 0A to compute tachyon scattering amplitudes in a background with a RR flux. We find that after the string coupling is multiplicatively renormalized, the amplitudes in any genus become polynomial in the RR flux. We propose that in the limit where both the string coupling and the RR flux go to infinity, the theory has a weaklycoupled description in terms of another superstring theory with a vanishingly small RR flux. This duality exchanges the inverse string coupling and the 0brane charge. The dual superstring theory must have a peculiar property that its only fieldtheoretic degree of freedom is a massless RR scalar. 1 1
