Questions tagged [ads-cft]

AdS/CFT is a special case of the holographic principle. It states that a quantum gravitating theory in Anti-de-Sitter (AdS) space is exactly equivalent to the gauge theory/Conformal Field Theory (CFT) on its boundary.

The AdS/CFT correspondence is a special case of the holographic principle. It states that a quantum gravitating theory in Anti-de-Sitter (AdS) space is exactly equivalent to the gauge theory/Conformal Field Theory (CFT) on its boundary.

Use this tag for questions pertaining to the AdS/CFT correspondence, matrix models, etc.

It is also known as Maldacena Duality or Gauge-Gravity Duality. It is commonly applied in the context of string theory, and has given rise to various important results. Notable examples include:

  • BFSS Matrix theory, also known as M(atrix) theory.

  • Matrix Type IIA string theory.

  • Matrix Horava-Witten string theory.

Note, however, that all three of these were discovered before AdS/CFT was. Maldacena proposed AdS/CFT as a generalisation of these examples.

Universal central charge in higher dimensional AdS/CFT?

In the $AdS_3/CFT_2$ correspondence, the central charge of the dual CFT2 is universally given by $$ c = \frac{3\ell}{2G} $$ This is independent of the matter in the bulk of AdS3. Is it also universal in the higher dimensional analogues…

Has AdS/CFT any predictive power in the natural context?

Has AdS/CFT any predictive power in the case of the space-time as we know it and in the case of reality as we know it experimentally? I may add: AdS/CFT in the interpretation given from the perspective of heavy ion collisions has been falsified (I…

A basic question on AdS/CFT

Previously I asked a question Question on dimensions of CFT operators (ref: MAGOO, hep-th/9905111) here and it was (correctly of course) answered by Motl. I realized I didn't understand a part of it even though I thought I did. It was about…

Ads/CFT coordinates

I have an AdS space written in Poincare' coordinates and in global coordinates. The transformation that brings one set in the other is a conformal transformation?

Worldvolume vs boundary in AdS/CFT

The original AdS5/CFT4 correspondence is usually claimed to match near-horizon supergravity -rather IIB string theory- with a "boundary" super Yang-Mills theory at $T=0$, i.e. in a Minkowski spacetime without matter. But the stacked/parallel brane…

Are there AdS/CFT duals all the way down?

Last night I was thinking about the AdS/CFT correspondence, and I thought of the following scenario: Consider a 4D AdS universe with only a single black hole. Assuming the bulk and boundary are perfectly dual, then we expect just a single black hole…

AdS/CFT at small and large central charge

We know that the AdS/CFT duality is a valid correspondence for large central charge (in the semi-classical limit). If this duality is valid for small central charge (in the quantum regime) is unclear. It is often said that a high energy CFT state…

What is the meaning of weakly coupled in gravity theories?

In a Colloquium lecture of Juan Maldecena, He states that weak coupling states the theory is hard to change the metric. And tolds that weakly coupled system requires a lot of fields. Can you give me more explanation for weakly coupled in gravity…
