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 ..."

macroscopic strings as heavy (anti)quark probes. The macroscopic strings are semiinfinite Type IIB strings ending on D3brane worldvolume. We first study deformation and fluctuation of D3brane when a macroscopic BPS string is attached. We find that both dynamics and boundary conditions agree with those
Black Hole Entropy Function, Attractors and Precision Counting of Microstates
, 2007
"... In these lecture notes we describe recent progress in our understanding of attractor mechanism and entropy of extremal black holes based on the entropy function formalism. We also describe precise computation of the microscopic degeneracy of a class of quarter BPS dyons in N = 4 supersymmetric strin ..."

AdS3 Black Holes and a Stringy Exclusion Principle
, 1998
"... The duality relating nearhorizon microstates of black holes obtained as orbifolds of a subset of AdS3 to the states of a conformal field theory is analyzed in detail. The SL(2, R)L ⊗ SL(2, R)R invariant vacuum on AdS3 corresponds to the NSNS vacuum of the conformal field theory. The effect of the ..."

of the orbifolding is to produce a density matrix, the temperature and entropy of which coincide with the black hole. For string theory examples the spectrum of chiral primaries agrees with the spectrum of multiparticle BPS states for particle numbers less than of order the central charge. An upper bound on the BPS
Supersymmetric worldvolume action for nonBPS
 Dbranes,” JHEP
, 1999
"... We construct the worldvolume action for nonBPS Dbranes in type II string theories. This action is invariant under all the unbroken supersymmetries in the bulk, but these symmetries are realised as spontaneously broken symmetries in the worldvolume theory. Coupling of this action to background su ..."

NonBPS states and branes in string theory
"... We review the recent developments in our understanding of nonBPS states and branes in string theory. The topics include 1) construction of unstable nonBPS Dbranes in type IIA and type IIB string theories, 2) construction of stable nonBPS Dbranes on various orbifolds and orientifolds of type II ..."

Corrections to Macroscopic Supersymmetric BlackHole Entropy
, 1998
"... We determine the corrections to the entropy of extremal black holes arising from terms quadratic in the Riemann tensor in N = 2; D = 4 supergravity theories. We follow Wald's proposal to modify the BekensteinHawking area law. The new entropy formula, whose value only depends on the electric/ma ..."

For string effective field theories arising from CalabiYau compactifications, our result for the entropy of a certain class of extremal blackhole solutions fully agrees with the counting
BPS Action and Superpotential for Heterotic String Compactifications with Fluxes
, 2003
"... We consider N = 1 compactifications to four dimensions of heterotic string theory in the presence of fluxes. We show that up to order O (α ′2) the associated action can be written as a sum of squares of BPSlike quantities. In this way we prove that the equations of motion are solved by backgrounds ..."

We study several classic gauge field configurations, including point charges in any worldvolume dimension and vortices in two worldvolum ..."

BPS nature of 3string junctions

These solutions are interpreted as describing planar 3string junctions, which arise because the original Dstring is deformed by the presence of the inserted charge. We compute the ..."
