Deforming field theories with U ( 1 ) × U ( 1 ) global symmetry and their gravity duals

چکیده
We find the gravity dual of a marginal deformation of N = 4 super Yang Mills, and discuss some of its properties. This deformation is intimately connected with an SL(2, R) symmetry of the gravity theory. The SL(2, R) transformation enables us to find the solutions in a simple way. These field theory deformations, sometimes called β deformations, can be viewed as arising from a star product. Our method works for any theory that has a gravity dual with a U(1) × U(1) global symmetry which is realized geometrically. These include the field theories that live on D3 branes at the conifold or other toric singularities, as well as their cascading versions.

A simple class of N = 3 gauge / gravity duals Daniel
We find the gravity duals to an infinite series of N = 3 Chern-Simons quiver theories. They are AdS4 ×M7 vacua of M-theory, with M7 in a certain class of 3-SasakiEinstein manifolds obtained by a quotient construction. The field theories can be engineered from a brane configuration; their geometry is summarized by a “hyperKähler toric fan” that can be read off easily from the relative angles of ...

متن کاملAdS4/CFT3 duals from M2-branes at hypersurface singularities and their deformations
We construct three-dimensional N = 2 Chern-Simons-quiver theories which are holographically dual to the M-theory Freund-Rubin solutions AdS4 × V5,2/Zk (with or without torsion G-flux), where V5,2 is a homogeneous Sasaki-Einstein seven-manifold. The global symmetry group of these theories is generically SU(2) × U(1) × U(1)R, and they are hence non-toric. The field theories may be thought of as t...
متن کاملBosonization of a Topological Coset Model and Non-critical String Theory
We analyze the relation between a topological coset model based on super SL(2, R)/U(1) coset and non-critical string theory by using free field realization. We show that the twisted N = 2 algebra of the coset model can be naturally transformed into that of noncritical string. The screening operators of the coset models can be identified either with those of the minimal matters or with the cosmo...
