Islands in linear dilaton black holes
Journal of High Energy Physics, 2021 We derive a novel four-dimensional black hole with planar horizon that asymptotes to the linear dilaton background. The usual growth of its entanglement entropy before Page’s time is established.

Extremal Black Holes as Bound States [PDF]
, 1995 We consider a simple static extremal multi-black hole solution with constituents charged under different $U(1)$ fields. Each of the constituents by itself is an extremal dilatonic black hole of coupling $a=\srt$.

(Non-adiabatic) string creation on nice slices in Schwarzschild black holes
Journal of High Energy Physics, 2017 Nice slices have played a pivotal role in the discussion of the black hole information paradox as they avoid regions of strong spacetime curvature and yet smoothly cut through the infalling matter and the outgoing Hawking radiation, thus, justifying the ...

Extremal black holes, Stueckelberg scalars and phase transitions
Journal of High Energy Physics, 2018 We calculate the entropy of a static extremal black hole in 4D gravity, non-linearly coupled to a massive Stueckelberg scalar. We find that the scalar field does not allow the black hole to be magnetically charged.

Stringy Corrections to Kaluza-Klein Black Holes [PDF]
, 1997 We consider string theory corrections to 4D black holes which solve the 5D vacuum Einstein equations. We find that the corrections vanish only for the extremal electric solution.

Asymptotic quasinormal modes of string-theoretical d-dimensional black holes
Journal of High Energy Physics, 2021 We compute the quasinormal frequencies of d-dimensional spherically symmetric black holes with leading string α′ corrections for tensorial gravitational perturbations in the highly damped regime.

Are There Topological Black Hole Solitons in String Theory?
, 1996 We point out that the celebrated Hawking effect of quantum instability of black holes seems to be related to a nonperturbative effect in string theory. Studying quantum dynamics of strings in the gravitational background of black holes we find classical ...

Entropy Function for Non-Extremal Black Holes in String Theory [PDF]
, 2007 We generalize the entropy function formalism to five-dimensional and four-dimensional non-extremal black holes in string theory. In the near horizon limit, these black holes have BTZ metric as part of the spacetime geometry.

Nuclear Physics B, 1989 The field equations, which emerge from string theory, are solved to leading order in α′ for the case of black hole space-times. We show how the results fit into a broader outlook on string theory and quantum gravity. In particular, it seems that string theory could cure some of the paradoxes associated with black hole evaporation.

Dynamically and thermodynamically stable black holes in Einstein-Maxwell-dilaton gravity
Journal of High Energy Physics, 2020 We consider Einstein-Maxwell-dilaton gravity with the non-minimal exponential coupling between the dilaton and the Maxwell field emerging from low energy heterotic string theory.
