Two-Boundaries AdS/CFT Correspondence in Dilatonic Gravity
Shin'ichi Nojiri, Sergei D. Odintsov
We discuss dilatonic gravity (bulk theory) from the point of view of (generalized) AdS/CFT correspondence. Self-consistent dilatonic background is considered. It may be understood…
Conformal Anomaly for Dilaton Coupled Theories from AdS/CFT Correspondence
Shin'ichi Nojiri, Sergei D. Odintsov
Trace anomaly for dilaton coupled conformal theories on curved background with non-zero dilaton is found from supergravity side as an IR effect using AdS/CFT correspondence. For $d…
Quantum generation of Schwarzschild-de Sitter (Nariai) black holes in effective dilaton-Maxwell gravity
Andrei A. Bytsenko, Shin'ichi Nojiri, Sergei D. Odintsov
Dilaton coupled electromagnetic field is essential element of low-energy string effective action or it may be considered as result of spherical compactification of Maxwell theory i…
Dynamical symmetry restoration for a higher-derivative four-fermion model in an external electromagnetic field
E. Elizalde, S. P. Gavrilov, S. D. Odintsov +1
A four-fermion model with additional higher-derivative terms is investigated in an external electromagnetic field. The effective potential in the leading order of large-N expansion…
Asymptotics of Elliptic Genera of Symmetric Products and Dyonic Black Hole Degeneracy
A. A. Bytsenko, A. E. Goncalves, S. D. Odintsov
We calculate asymptotic expansions of elliptic genera for a supersymmetric sigma model on the N - fold symmetric product S^NM of a Kahler manifold M and for N = 2 superconformal fi…
Quantum (in)stability of 2D charged dilaton black holes and 3D rotating black holes
Shin'ichi Nojiri, Sergei D. Odintsov
The quantum properties of charged black holes (BHs) in 2D dilaton-Maxwell gravity (spontaneously compactified from heterotic string) with dilaton coupled scalars are studied. W…
