Evaporation of regular black holes in 2D dilaton gravity
read the original abstract
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 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 anti-trapped regions after the primary black hole becomes un-trapped. Numerical simulations of microscopic black holes yield a final spacetime that is free of apparent horizons and Cauchy horizons. This would imply that the evaporation of regular black holes is a unitary process.

Regular Black Holes in Nonlocal Quasitopological Gravity
Infinite-derivative completions of quasitopological gravities are ghost-free, avoid strong coupling, and admit exact spherically symmetric vacuum regular black holes obeying a perturbative Birkhoff theorem.

Semiclassical regularity of compact trapped regions: From dynamical horizons to inner extremality
In finite-lifetime dynamical geometries the in-vacuum RSET stays finite at the inner horizon, growing exponentially for non-extremal cases but only as a power law for inner-extremal ones.

Regular Vaidya solutions of effective gravitational theories
Regular Vaidya solutions exist in effective gravitational theories that dynamically describe radiation-driven formation of regular black holes or mimickers without curvature singularities.

Anomaly-driven evaporation endpoints of a two-dimensional regular black hole
The FFN dilaton-coupled anomaly model applied to the 2D Bardeen-like black hole enforces r_∞=√2 ℓ for quiescent finite-radius branches and excludes most null branches except the borderline p=2 power-law case under str...
