چکیده
Chiral symmetry breaking in a non-local Nambu-Jona-Lasinio like 4-fermi model, derived from the intersecting brane model of Sakai and Sugimoto in the weak coupling limit, was found to occur only above a critical value of the coupling. Numerical investigations showed, contrary to what had been suggested in the literature, that this feature persists even when the radius of the circle on which the D4-branes wrap is taken to infinity.

A connection was established between long wavelength solutions of the classical theory of gravity in AdSd+1 and the Navier Stokes equations in d dimensions. A map (probably one to one) was constructed from the space of long wavelength solutions to Einstein’s equations in AdSd+1 to the solution space of fluid dynamics in d dimensions. These results may prove important in understanding the dynami...

In type II string theories, intersecting brane constructions were proposed that contain braneantibrane pairs suspended between 5-branes. Various models with distinct physics were identified: parallel brane-antibrane pairs, adjacent pairs, non-adjacent pairs, and ”Borromean” configurations which break all supersymmetry even though any pair of branes preserves some supersymmetry. Some of the bran...

Research in String Theory was carried out on a very broad front, encompassing mirror symmetry, matrix models, duality, compactifications, the study of string theory in a curved background and its relation to gauge theories, and the interaction of string theory with cosmology. Some progress was made towards quantizing string theory in AdS5 × S in the limit of zero curvature, which is dual to the...

Using the AdS/CFT correspondence, a complete theory of superfluid hydrodynamics for s-wave superfluids was obtained generalizing classic earlier results by Landau, Tiza and Putterman. A new class of small hairy black holes was found in AdS5 x S. The hydrodynamic properties of strongly coupled SU(N) Yang-Mills theory of the D1-brane was studied at finite temperature and at a nonzero density of R...

Patterns produced by adding grains at a single site on a flat substrate in sandpile models provide nice examples of complex patterns produced from simple deterministic local nonlinear evolution rules. The authors have earlier studied some of the patterns in abelian sandpile models on the two-dimensional Manhattan lattice and the F-lattice. These results were extended to the case with multiple s...
