چکیده

Conformal scalar fields coupled to the dilaton appear naturally in two-dimensional models of black hole evaporation. We show that their trace anomaly is (1/24π)[R− 6(∇φ)2 − 22φ]. It follows that the RST counterterm appears naturally in the one-loop effective action. [email protected] [email protected]

Conformal scalar fields coupled to the dilaton appear naturally in two-dimensional models of black hole evaporation. We show that their trace anomaly is (1/24π)[R − 6(∇φ)2 − 22φ]. It follows that an RST-type counterterm appears naturally in the one-loop effective action. [email protected] [email protected]

Conformal Anomaly for Dilaton Coupled Theories from AdS/CFT Correspondence

Trace anomaly for dilaton coupled conformal theories on curved background with non-zero dilaton is found from supergravity side as an IR e ect using AdS/CFT correspondence. For d = 2 it coincides with the conformal anomaly for dilaton coupled scalar (up to total derivative term which is known to be ambiguous). In four-dimensional case we get conformal anomaly for N = 4 super YM theory interacti...

Effective action and Hawking radiation for dilaton coupled scalars in two dimensions

The effective one-loop action for general dilaton theories with arbitrary dilaton-dependent measure and nonminimal coupling to scalar matter is computed. As an application we determine the Hawking flux to infinity from black holes in D-dimensions. We resolve the recently resurrected problem of an apparent negative flux for nonminimally coupled scalars: For any D ≥ 4 Black Hole the complete flux...

INFLATIONARY DILATONIC de SITTER UNIVERSE FROM SUPER YANG - MILLS THEORY PERTURBED BY SCALARS AND SPINORS

In this paper a quantum N = 4 super Yang-Mills theory perturbed by dilaton-coupled scalars and spinor fields, is considered. The induced effective action for such a theory is calculated on a dilaton-gravitational background using the conformal anomaly found via the AdS/CFT correspondence. Considering such an effective action (using the large N method) as a quantum correction to the classical gr...
