M theory, orientifolds and G - flux

- K. Dasgupta, G. Rajesh, S. Sethi
- Physics
- 12 August 1999

We study the properties of M and F theory compactifications to three and four dimensions with background fluxes. We provide a simple construction of supersymmetric vacua, including some with… Expand

Matrix perturbation theory for M-theory on a PP-wave

- K. Dasgupta, M. M. Sheikh-Jabbari, M. Raamsdonk
- Physics
- 19 May 2002

In this paper, we study the matrix model proposed by Berenstein, Maldacena, and Nastase to describe M-theory on the maximally supersymmetric pp-wave. We show that the model may be derived directly as… Expand

D3-D7 inflationary model and M theory

- K. Dasgupta, C. Herdeiro, S. Hirano, R. Kallosh
- Physics
- 3 March 2002

A proposal is made for a cosmological D3-D7 model with a constant magnetic flux along the D7 world volume. It describes an $\mathcal{N}=2$ gauge model with Fayet-Iliopoulos terms and the potential of… Expand

Five easy pieces: The dynamics of quarks in strongly coupled plasmas

- Mohammed Mia, K. Dasgupta, C. Gale, S. Jeon
- Physics
- 10 February 2009

Abstract We revisit the analysis of the drag a massive quark experiences and the wake it creates at a temperature T while moving through a plasma using a gravity dual that captures the… Expand

F-theory at Constant Coupling

- K. Dasgupta, S. Mukhi
- Physics
- 10 June 1996

The subspace of the moduli space of F-theory on K3 over which the coupling remains constant develops new branches at special values of this coupling. These values correspond to fixed points under the… Expand

Orbifolds of M-theory

- K. Dasgupta, S. Mukhi
- Physics
- 24 December 1995

Abstract We study Z 2 -orbifolds of 11-dimensional M-theory on tori of various dimensions. The most interesting model (besides the known S 1 / Z 2 case) corresponds to T 5 / Z 2 for which we argue… Expand

Brane constructions, fractional branes and anti-deSitter domain walls

- K. Dasgupta, S. Mukhi
- Physics
- 20 April 1999

Compactifications of type IIB string theory on AdS5X5, where X5 is an Einstein space, can have one-fourth or half maximal supersymmetry for certain choices of X5. Some of these theories admit exotic… Expand

Nonlocal field theories and their gravity duals

- Aaron Bergman, K. Dasgupta, O. Ganor, J. Karczmarek, G. Rajesh
- Physics
- 13 March 2001

The gravity duals of nonlocal field theories in the large-N limit exhibit a novel behavior near the boundary. To explore this, we present and study the duals of dipole theories, a particular class of… Expand

Noncommutative Dipole Field Theories

- K. Dasgupta, M. M. Sheikh-Jabbari
- Physics
- 9 December 2001

Assigning an intrinsic constant dipole moment to any field, we present a new kind of associative star product, the dipole star product, which was first introduced in [hepth0008030]. We develop the… Expand

BPS nature of 3-string junctions

- K. Dasgupta, S. Mukhi
- Physics
- 13 November 1997

We study BPS-saturated classical solutions for the world-sheet theory of a D-string in the presence of a point charge. These solutions are interpreted as describing planar 3-string junctions, which… Expand
