A Note on the Bach Tensor in AdS/CFT
نویسندگان
چکیده
The relationship between Bach’s tensor and the four dimensional conformal anomaly is clarified, as well as its rôle as an obstruction for a perturbative reconstruction of the hologram (a Dirichlet problem). Some considerations on the obstruction in higher dimensions are included and, in particular, a candidate for the Fefferman-Graham obstruction in six dimensional space is constructed.

Massive symmetric tensor field on AdS
The two-point Green function of a local operator in CFT corresponding to a massive symmetric tensor field on the AdS background is computed in the framework of the AdS/CFT correspondence. The obtained two-point function is shown to coincide with the two-point function of the graviton in the limit when the AdS mass vanishes.
متن کاملBlack Holes, Shock Waves, and Causality in the AdS/CFT Correspondence
We find the expectation value of the energy-momentum tensor in the CFT corresponding to a moving black hole in AdS. Boosting the black hole to the speed of light, keeping the total energy fixed, yields a gravitational shock wave in AdS. The analogous procedure on the field theory side leads to “light cone” states, i.e., states with energy-momentum tensor localized on the light cone. The corresp...
متن کاملGeneralized free fields and the AdS-CFT correspondence
Motivated by structural issues in the AdS-CFT correspondence, the theory of generalized free fields is reconsidered. A stress-energy tensor for the generalized free field is constructed as a limit of Wightman fields. Although this limit is singular, it fulfils the requirements of a conserved local density for the Poincaré generators. An explicit “holographic” formula relating the Klein-Gordon f...
متن کاملبررسی حرکت براونی یک ذره سنگین با استفاده از تناظر AdS/CFT
In this research we have studied the Brownian motion of a heavy particle in thermalized plasma. This plasma is made of quarks and gluons and it is different with normal plasma. Since, coupling constant is strong in this plasma, usual perturbation method does not work for the study of this plasma. For this purpose AdS/CFT duality is used. Based on the AdS/CFT duality to consider temperature...
متن کاملAdS / CFT and quantum - corrected brane entropy
It is shown that quantum-induced (inflationary) brane Universe occurs in the bulk 5d AdS black hole in accordance with AdS/CFT correspondence. Brane stress tensor is induced by quantum effects of dual CFT and brane crosses the horizon of AdS black hole. Quantum-corrected Hubble constant, Hawking temperature and entropy are found on the brane (and at the horizon). The similarity between CFT entr...
