IR Renormalisation of General Effective Actions and Hawking Flux in 2D Gravity Theories
D. Hofmann, W. Kummer
The infrared problem of the effective action in 2D is discussed in the framework of the Covariant Perturbation Theory. The divergences are regularised by a mass and the leading ter…
Effective Action and Hawking Flux from Covariant Perturbation Theory
D. Hofmann, W. Kummer
The computation of the radiation flux related to the Hawking temperature of a Schwarzschild Black Hole or another geometric background is still well-known to be fraught with a numb…
Quantum Radiation from Black Holes
Daniel Hofmann
The expectation value of the energy-momentum tensor and the Hawking flux of a scalar field on a Schwarzschild spacetime is calculated using the zeta-function regularisation of the…
Two-Dilaton Theories in Two Dimensions from Dimensional Reduction
D. Grumiller, D. Hofmann, W. Kummer
Dimensional reduction of generalized gravity theories or string theories generically yields dilaton fields in the lower-dimensional effective theory. Thus at the level of D=4 theor…
