Hawking Radiation in the Dilaton Gravity with a Non-minimally Coupled Scalar Field
نویسنده
چکیده
We discuss the two-dimensional dilaton gravity with a scalar field as the source matter where the coupling with gravity is given, besides the minimal one, through an external field. This coupling generalizes the conformal anomaly in the same way as those found in recent literature, but with a diferent motivation. The modification to the Hawking radiation is calculated explicity and show an additional term that introduces a dependence on the (effective) mass of the black-hole.

متن کاملDilaton Gravity with a Non-minimally Coupled Scalar Field
We discuss the two-dimensional dilaton gravity with a scalar field as the source matter. The coupling between the gravity and the scalar, massless, field is presented in an unusual form. We work out two examples of these couplings, and solutions with black-hole behaviour are discussed and compared with those found in the literature.
متن کاملHawking Radiation for Non-minimally Coupled Matter from Generalized 2D Black Hole Models
It is well known that spherically symmetric reduction of General Relativity (SSG) leads to non-minimally coupled scalar matter. We generalize (and correct) recent results to Hawking radiation for a class of dilaton models which share with the Schwarzschild black hole nonminimal coupling of scalar fields and the basic global structure. An inherent ambiguity of such models (if they differ from SS...
متن کاملTachyon field quantization and Hawking radiation.
Abstact We quantize the tachyon field in a static two dimensional dilaton gravity black hole background,and we calculate the Hawking radiation rate.We find that the thermal radiation flux,due to the tachyon field, is larger than the conformal matter one.We also find that massive scalar fields which do not couple to the dilaton,do not give any contribution to the thermal radiation, up to terms q...
متن کاملConformal Equivalence of 2d Dilaton Gravity Models
We investigate the behavior of generic, matter-coupled, 2D dilaton gravity theories under dilaton-dependent Weyl rescalings of the metric. We show that physical observables associated with 2D black holes, such as the mass, the temperature and the flux of Hawking radiation are invariant under the action of both Weyl transformations and dilaton reparametrizations. The field theoretical and geomet...
