Supergravity with Self-dual B fields and Instantons in Noncommutative Gauge Theory

S. R. Das, S. Kalyana Rama, S. P. Trivedi

We study Type IIB supergravity in the presence of (euclidean) D3 branes and nonzero self-dual B-fields. We point out that the Einstein frame metric is identical to the full geometr…

D1/D5 System with B-field, Noncommutative Geometry and the CFT of the Higgs Branch

Avinash Dhar, Gautam Mandal, Spenta R. Wadia +1

The D1/D5 system is considered in the presence of the NS B field. An explicit supergravity solution in the asymptotically flat and near horizon limits is presented. Explicit mass f…

Instantons and Chiral Anomaly in Fuzzy Physics

A. P. Balachandran, S. Vaidya

In continuum physics, there are important topological aspects like instantons, theta-terms and the axial anomaly. Conventional lattice discretizations often have difficulties in tr…

Killing Spinors and Supersymmetric AdS Orbifolds

Bahniman Ghosh, Sunil Mukhi

We examine the behaviour of Killing spinors on AdS5 under various discrete symmetries of the spacetime. In this way we discover a number of supersymmetric orbifolds, reproducing th…

Gravitational Couplings, Orientifolds and M-Planes

Sunil Mukhi, Nemani V. Suryanarayana

We examine string-theory orientifold planes of various types including the Sp and SO-odd planes, and deduce the gravitational Chern-Simons couplings on their world-volumes. Consist…

D1/D5 Moduli in SCFT and Gauge Theory, and Hawking Radiation

Justin R. David, Gautam Mandal, Spenta R. Wadia

We construct marginal operators of the orbifold SCFT corresponding to all twenty near-horizon moduli in supergravity, including operators involving twist fields which correspond to…

Point Mass Geometries, Spectral Flow and AdS_3-CFT_2 Correspondence

Justin R. David, Gautam Mandal, Sachindeo Vaidya +1

We discuss, in terms of the AdS_3-CFT_2 correspondence, a one-parameter family of (asymptotically AdS_3) conical geometries which are generated by point masses and interpolate betw…

Brane Constructions, Fractional Branes and Anti-deSitter Domain Walls

Keshav Dasgupta, Sunil Mukhi

Compactifications of type IIB string theory on AdS5 x X5, where X5 is an Einstein space, can have one-fourth or half maximal supersymmetry for certain choices of X5. Some of these…

Negative Screenings in Conformal Field Theory and 2D Gravity: The Braiding Matrix

J. Rasmussen, J. Schnittger

We consider an extension of the Coulomb gas picture which is motivated by Liouville theory and contains negative powers of screening operators on the same footing as positive ones.…

Anti-de Sitter gravity associated with the supergroup

Justin R. David

We construct the anti-de Sitter supergravity in three dimensions associated with the supergroup . The field content and the action are inferred using the…

The BPS Spectra of Gauge Theories in Two and Four Dimensions

N. Dorey, T. J. Hollowood, D. Tong

We study N=(2,2) supersymmetric abelian gauge theories in two dimensions. The exact BPS spectrum of these models is shown to coincide with the spectrum of massive hypermultiplets o…

Probing D0-D6 Black Hole Configuration: 2-Loop Matrix Theory Correction to D0-Brane Effective Action

Avinash Dhar

We present a calculation of the matrix theory 2-loop effective action for a D0-brane in the background of the recently discussed D0-D6 bound state configuration. The effective DBI…

A Note on 1/4-BPS States

David Tong

We study classical solutions of N=4 super Yang-Mills theories that are invariant under 1/4 of the supersymmetry generators. Expressions for the mass and electric charge of the conf…

Brane Waves, Yang-Mills theories and Causality

Sumit R. Das

We provide evidence for the validity of AdS/CFT correspondence in the Coulomb branch by comparing the Yang-Mills effective action with the potential between waves on two separated…
