Holographic Gauge Theories in Background Fields And Surface Operators

چکیده
We construct a new class of supersymmetric surface operators in N = 4 SYM and find the corresponding dual supergravity solutions. We show that the insertion of the surface operator – which is given by a WZW model supported on the surface – appears by integrating out the localized degrees of freedom along the surface which arise microscopically from a D3/D7 brane intersection. Consistency requires constructing N = 4 SYM in the D7 supergravity background and not in flat space. This enlarges the class of holographic gauge theories dual to string theory backgrounds to gauge theories in non-trivial supergravity backgrounds. The dual Type IIB supergravity solutions we find reveal – among other features – that the holographic dual gauge theory does indeed live in the D7-brane background. 10/2007 1 [email protected] 2 [email protected] 3 [email protected]

From Surface Operators to Non-Abelian Volume Operators in Puff Field Theory
Puff field theory (PFT) is a low energy decoupling regime of string theory that still retains the nonlocal attributes of the parent theory—while preserving isotropy for its nonlocal degrees of freedom. It realizes an extended holographic dictionary at strong coupling and dynamical nonlocal states akin to defects or the surface operators of local gauge theories. In this work, we probe the nonloc...
متن کاملNon - Critical String Duals of N = 1 Quiver Theories
We construct N =1 non-critical strings in four dimensions dual to strongly coupled N=1 quiver gauge theories in the Coulomb phase, generalizing the string duals of Argyres-Douglas superconformal fixed points in N=2 gauge theories. They are the first examples of superstring vacua with an exact worldsheet description dual to chiral N=1 theories. We identify the dual of the non-critical superstrin...
متن کاملBeyond the pp-Wave
In a certain kinematic limit, where the effects of spacetime curvature (and other background fields) greatly simplify, the light-cone gauge world-sheet action for a type IIB superstring on AdS5 × S reduces to that of a free field theory. It has been conjectured by Berenstein, Maldacena, and Nastase that the energy spectrum of this string theory matches the dimensions of operators in the appropr...
متن کاملInstantons and Emergent Geometry
Gravity is a mysterious force; we still don’t know what gravity is. But recent developments from string and M theories gradually reveal an intriguing picture on gravity (for recent reviews, see, for example, [1, 2]): Gravity may be a collective phenomenon emergent from gauge fields. That is, the spin-two graviton might arise as a composite of two spin-one gauge bosons. Although the emergent gra...
متن کاملWilson loops as Precursors Leonard Susskind and Nicolaos Toumbas
There is substantial evidence that string theory on AdS5 × S5 is a holographic theory in which the number of degrees of freedom scales as the area of the boundary in Planck units. Precisely how the theory can describe bulk physics using only surface degrees of freedom is not well understood. A particularly paradoxical situation involves an event deep in the interior of the bulk space. The event...
