Hawking Radiation in Trace Anomaly Free Frames
نویسنده
چکیده
We have used the results of renormalization of a two-dimensional quantum stress tensor to develop a conformally invariant dynamical model. The model requires the consideration of those conformal frames in which there exists a correspondence between the trace anomaly and a cosmological constant. We apply this model to a two dimensionalSchwarzschild (-de Sitter) spacetime to show that in these conformal frames one may achieve Hawking radiation without recourse to the trace anomaly .

Hawking Radiation and Quantum Anomaly in AdS2/CFT1 Correspondence
In order to understand a boundary description of Hawking radiation in AdS/CFT correspondence, we investigate the trace anomaly method in AdS2 space. In this method, Hawking radiation is derived from the trace anomaly of energy-momentum tensor in the bulk. We find a correspondence between the energy-momentum tensor and a composite operator in CFT1 and understand the anomalous properties of the e...
متن کامل0 Casimir Effect , Hawking Radiation and Trace Anomaly
The Casimir energy for massless scalar field of two parallel conductor, in two dimensional Schwarzchild black hole background, with Dirichlet boundary conditions is calculated by making use of general properties of renormalized stress tensor. We show that vacuum expectation value of stress tensor can be obtain by Casimir effect, trace anomaly and Hawking radiation. Four-dimensional of this prob...
متن کاملHawking Radiation from Rotating Black Holes and Gravitational Anomalies
We study the Hawking radiation from Rotating black holes from gravitational anomalies point of view. First, we show that the scalar field theory near the Kerr black hole horizon can be reduced to the 2-dimensional effective theory. Then, following Robinson and Wilczek, we derive the Hawking flux by requiring the cancellation of gravitational anomalies. We also apply this method to Hawking radia...
متن کاملHawking Radiation, Covariant Boundary Conditions and Vacuum States
The basic characteristics of the covariant current < Jμ > and the covariant energymomentum tensor < Tμν > in Unruh, Hartle-Hawking and Boulware states are obtained from a chiral effective action. These results are used to justify the covariant boundary condition used in recent approaches [2, 4, 5, 6] of computing the Hawking flux from chiral gauge and gravitational anomalies. We also discuss a ...
متن کاملHawking Radiation via Higher-spin Gauge Anomalies
We give a higher-spin generalization of the anomaly method for the Hawking radiation from black holes. In the paper [13] higher-spin generalizations of the gauge (and gravitational) anomalies in d=2 were obtained. By applying these anomalies to black hole physics, we derive the higher moments of the Hawking fluxes. We also give a higher-spin generalization of the trace anomaly method by Christe...
