Quantum-Corrected Bondi Mass for 2D Hawking Radiation
Jonathan Barenboim, Andrei V. Frolov, Gabor Kunstatter
We derive the Hamiltonian for general semi-classical 2D dilaton gravity, beginning with the complete action including the Polyakov action and Gibbons-Hawking-York boundary term. Th…

Evaporation of regular black holes in 2D dilaton gravity
Jonathan Barenboim, Andrei V. Frolov, Gabor Kunstatter
We present a general class of non-singular black holes in semi-classical, two-dimensional dilaton gravity, with a focus on a Bardeen-like model. The equations of motion for an evap…

No Drama in 2D Black Hole Evaporation
Jonathan Barenboim, Andrei V. Frolov, Gabor Kunstatter
We numerically calculate the spacetime describing the formation and evaporation of a regular black hole in 2D dilaton gravity. The apparent horizons evaporate smoothly in finite ti…
