Nonlinear electroweak sphaleron clouds around Kerr black holes
Carlos Herdeiro, Jutta Kunz, Hendrik Mennenga +1
Kerr black holes and electroweak sphalerons are remarkable solutions of two pillars of modern physics: General Relativity and the Standard Model of particle physics, respectively.…

Quartic Scalar Clouds on Fixed Kerr Backgrounds
Hendrik Mennenga
We study stationary nonlinear clouds of a complex scalar field on fixed Kerr and Schwarzschild backgrounds, with an unbounded scalar potential. On Kerr backgrounds we find finite-a…
