Evaporation of regular black holes in 2D dilaton gravity

We present a general class of nonsingular black holes in semiclassical, two-dimensional dilaton gravity, with a focus on a Bardeen-like model. The equations of motion for an evaporating black hole including backreaction are solved numerically. The apparent horizons evaporate smoothly in finite time to form a compact trapped region. Backreaction effects lead to the formation of additional trapped and antitrapped regions after the primary black hole evaporates. Numerical simulations of microscopic black holes yield a final spacetime that is free of apparent horizons and Cauchy horizons, suggesting that the evaporation of regular 2D black holes is a unitary process.
