Bubbling supertubes and foaming black holes
We construct smooth BPS three-charge geometries that resolve the zero-entropy singularity of the $U(1)\ifmmode\times\else\texttimes\fi{}U(1)$ invariant black ring. This singularity is resolved by a geometric transition that results in geometries without any branes sources or singularities but with nontrivial topology. These geometries are both ground states of the black ring, and …
