Stringy Corrections to Kaluza-Klein Black Holes [PDF]
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.

We 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.

Phases and stability of non-uniform black strings
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.

Critical phenomena in the AdS/CFT duality
We review black holes with second-order phase transition in string theory (R-charged black holes and holographic superconductors) and review their static and dynamic critical phenomena.

Statistical Entropy of Nonextremal Four-Dimensional Black Holes and U-Duality [PDF]
We identify the states in string theory which are responsible for the entropy of near-extremal rotating four-dimensional black holes in $N=8$ supergravity. For black holes far from extremality (with no rotation), the Bekenstein-Hawking entropy is exactly

Three-dimensional black holes and string theory [PDF]
The exact decay rate for emission of massless minimally coupled scalar fields by a non-extremal black hole in 2+1 dimensions is obtained. At low energy, the decay rate into scalars with zero angular momentum is correctly reproduced within conformal field theory.

The artisanal underground: gold, subsistence, and subsurface materiality in Colombia
Abstract This article focuses on subsurface materiality to explore how small‐scale gold miners in Colombia navigate formal politics. In much critical research, the underground appears as a space of great developmentalist ambition, whose resources enable corporate expansion and bureaucratic rule.

From black strings to fundamental strings: non-uniformity and phase transitions
We discuss the transition between black strings and fundamental strings in the presence of a compact dimension, S z 1 $$ {\mathbbm{S}}_z^1 $$ . In particular, we study the Horowitz-Polchinski effective field theory in ℝ d × S z 1 $$ {\mathbb{R}}^d\times {

Resolving black-hole microstructure with new momentum carriers
All known horizonless black-hole microstate geometries correspond to brane sources that acquire a finite size, and hence break the spherical symmetry of the black hole. We construct, for the first time, solutions with zero horizon area that have the same

Noncommutative $D_3$-brane, Black Holes and Attractor Mechanism [PDF]
We revisit the 4D generalized black hole geometries, obtained by us [1], with a renewed interest, to unfold some aspects of effective gravity in a noncommutative D3-brane formalism. In particular, we argue for the existence of extra dimensions in the gravity decoupling limit in the theory.
