Spontaneous scalarization is a mechanism that allows black holes to develop a non-trivial profile of a scalar field “scalar hair” because of tachyonic instabilities, enabling tests of gravity beyond General Relativity.

Discussion of the paper "The Great Impersonation: W-Solitons as Prototypical Black Hole Microstates", by A. Dima et al.
