Entropy in the Russo-Susskind-Thorlacius model

Solvable Models for radiating Black Holes and Area - preserving Diffeomorphisms ∗

Solvable theories of 2D dilaton gravity can be obtained from a Liouville theory by suitable field redefinitions. In this paper we propose a new framework to generate 2D dilaton gravity models which can also be exactly solved in the semiclassical approximation. Our approach is based on the recently introduced scheme to quantize massless scalar fields coupled to 2D gravity maintaining invariance ...

Black hole mining in the RST model

Rohitvarma Basavaraju∗ and David A. Lowe† Department of Physics, Brown University, Providence, RI 02912, USA (Dated: November 8, 2016) Abstract We consider the possibility of mining black holes in the 1+1-dimensional dilaton gravity model of Russo, Susskind and Thorlacius. The model correctly incorporates Hawking radiation and backreaction in a semiclassical expansion in 1/N , where N is the nu...

Black Hole Evaporation by Thermal Bath Removal ∗

We study the evaporation process of 2D black holes in thermal equilibrium when the incoming radiation is turned off. Our analysis is based on two different classes of 2D dilaton gravity models which are exactly solvable in the semiclassical aproximation including back-reaction. We consider a one parameter family of models interpolating between the Russo-Susskind-Thorlacius and Bose-Parker-Peleg...

The Information Loss Problem of Black Hole and the First Order Phase Transition in String Theory

In recent years, Susskind, Thorlacius and Uglum have proposed the model for strings near a black hole horizon in order to represent the quantum mechanical entropy of the black hole and to solve the information loss problem. But, this model is insufficient because they did not consider the metric modification by massive strings and did not explain how to bring out the information from the inside...
