One-loop effective potential from higher-dimensional AdS black holes
نویسندگان
چکیده
We study the quantum effects in a brane-world model in which a constant curvature (in particular, a flat) brane universe is embedded in a higher-dimensional bulk AdS black hole, instead of the usual portion of the AdS5. By using zeta regularisation, we explicitly calculate the one-loop effective potential due to the bulk quantum fields and show that it leads to a non-vanishing cosmological constant, which can definitely acquire a positive value.

The Cardy-Verlinde Formula and AdS Black Holes
In a recent paper hep-th/0008140 by E. Verlinde, an interesting formula has been put forward, which relates the entropy of a conformal formal field in arbitrary dimensions to its total energy and Casimir energy. This formula has been shown to hold for the conformal field theories that have AdS duals in the cases of AdS Schwarzschild black holes and AdS Kerr black holes. In this paper we further...
متن کاملThe Thermodynamic Potentials of Kerr-AdS Black Holes and their CFT Duals
String or M-theory in the background of Kerr-AdS black holes is thought to be dual to the large N limit of certain conformal field theories on a rotating sphere at finite temperature. The five dimensional black hole is associated to N =4 supersymmetric Yang-Mills theory on a rotating three-sphere and the four dimensional one to the superconformal field theory of coinciding M2 branes on a rotati...

2 We present a detailed discussion of AdS 3 black holes and their connection to two-dimensional conformal field theories via the AdS/CFT correspondence. Our emphasis is on deriving refined versions of black hole partition functions, that include the effect of higher derivative terms in the spacetime action as well as non-perturbative effects. We include background material on gravity in AdS 3 ,...
متن کاملQuantum Horizons of the Standard Model Landscape
The long-distance effective field theory of our Universe—the Standard Model coupled to gravity— has a unique 4D vacuum, but we show that it also has a landscape of lower-dimensional vacua, with the potential for moduli arising from vacuum and Casimir energies. For minimal Majorana neutrino masses, we find a near-continuous infinity of AdS3×S1 vacua, with circumference ∼ 20 microns and AdS3 leng...
