Notes on islands in asymptotically flat 2d dilaton black holes
Journal of High Energy Physics, 2020 We study the islands and the Page curve in the 1+1-dimensional eternal dilaton black hole models. Without islands, the entanglement entropy of the radiation grows linearly at late time.

Ultra-spinning Chow’s black holes in six-dimensional gauged supergravity and their properties
Journal of High Energy Physics, 2021 By taking the ultra-spinning limit as a simple solution-generating trick, a novel class of ultra-spinning charged black hole solutions has been constructed from Chow’s rotating charged black hole with two equal-charge parameters in six-dimensional N ...

Phases and stability of non-uniform black strings
Journal of High Energy Physics, 2018 We construct solutions of non-uniform black strings in dimensions from D ≈ 9 all the way up to D = ∞, and investigate their thermodynamics and dynamical stability.

Journal of High Energy PhysicsWe consider coupled gravitational and electromagnetic perturbations of a family of five-dimensional Einstein-Maxwell solutions that describes both magnetized black strings and horizonless topological stars.

Black hole thermodynamics with dynamical lambda
Journal of High Energy Physics, 2017 We study evolution and thermodynamics of a slow-roll transition between early and late time de Sitter phases, both in the homogeneous case and in the presence of a black hole, in a scalar field model with a generic potential having both a maximum and a ...

Massive vector fields in Kerr-Newman and Kerr-Sen black hole spacetimes
Journal of High Energy Physics, 2020 The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein-Maxwell gravity (the Kerr- Newman solution) and low-energy heterotic string theory (the Kerr-Sen black hole).

Brickwall in rotating BTZ: a dip-ramp-plateau story
Journal of High Energy PhysicsIn this article, building on our recent investigations and motivated by the fuzzball-paradigm, we explore normal modes of a probe massless scalar field in the rotating BTZ-geometry in an asymptotically AdS spacetime and correspondingly obtain the ...

Phases of string stars in the presence of a spatial circle
Journal of High Energy PhysicsIn string theory, black holes are expected to transition into string stars as their Hawking temperatures approach the Hagedorn temperature. We study string stars and their phase transitions in the Euclidean spacetime ℝ d × S τ 1 $$ {\mathbbm{S}}_{\tau}^1

Microstates of non-extremal black holes: a new hope
Journal of High Energy PhysicsWe provide a new roadmap for constructing microstates of non-extremal black holes in supergravity. First, we review the non-linear sigma model of five-dimensional supergravity governing stationary solutions with a U(1) isometry and present the first ...

Journal of High Energy PhysicsWe construct, for the first time, new static non-extremal five-dimensional black hole solutions (without or with squashed horizons) endowing with four different electric charge parameters in the D = 5, N $$ \mathcal{N} $$ = 2 supergravity coupled to ...
