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

Constraints on low-dimensional string compactifications

Abstract We study the restrictions imposed by cancellation of the tadpoles for two-, three-, and four-form gauge fields in string theory, M-theory and F-theory compactified to two, three and four… Expand

D-Brane Bound States Redux

Abstract:We study the existence of D-brane bound states at threshold in Type II string theories. In a number of situations, we can reduce the question of existence to quadrature, and the study of a… Expand

Supersymmetry constraints on type IIB supergravity

Supersymmetry is used to derive conditions on higher derivative terms in the effective action of type IIB supergravity. Using these conditions, we are able to prove earlier conjectures that certain… Expand

A matrix big bang

- B. Craps, S. Sethi, E. Verlinde
- Physics
- 21 June 2005

The light-like linear dilaton background represents a particularly simple time-dependent 1/2 BPS solution of critical type-IIA superstring theory in ten dimensions. Its lift to M-theory, as well as… Expand

(0,2) Duality

We construct dual descriptions of (0,2) gauged linear sigma models. In some cases, the dual is a (0,2) Landau-Ginzburg theory, while in other cases, it is a non-linear sigma model. The duality map… Expand

The Higgs Branch of Impurity Theories

- A. Kapustin, S. Sethi
- Physics, Mathematics
- 1 April 1998

We consider supersymmetric gauge theories with impurities in various dimensions. These systems arise in the study of intersecting branes. Unlike conventional gauge theories, the Higgs branch of an… Expand

Supermanifolds, rigid manifolds and mirror symmetry

- S. Sethi
- Physics
- 29 April 1994

Abstract By providing a general correspondence between Landau-Ginzburg orbifolds and non-linear sigma models, we find that the elusive mirror of a rigid manifold is actually a supermanifold. We also… Expand

Saltatory relaxation of the cosmological constant

- J. Feng, J. March-Russell, S. Sethi, F. Wilczek
- Physics
- 30 May 2000

Abstract We modify and extend an earlier proposal by Brown and Teitelboim to relax the effective cosmological term by nucleation of branes coupled to a three-index gauge potential. Microscopic… Expand

A Relation Between N = 8 Gauge Theories in Three Dimensions

- S. Sethi
- Physics
- 22 September 1998

We show that three-dimensional N = 8 Sp(N) and SO(2N+1) gauge theories flow to the same strong coupling fixed point. As a consequence, the corresponding orientifold two-planes in type IIA string… Expand
