End state of the experimental black-hole bomb
Patrik Švančara, Leonardo Solidoro, Pietro Smaniotto +10
Rotating black holes can amplify incident waves through superradiant scattering. When these waves are confined, repeated amplification gives rise to the black-hole bomb instability…

Experimentally Resolving Gravity-Capillary Wave Evolution in Vessels of Unknown Boundary Conditions
Sean M. D. Gregory, Vitor S. Barroso, Silvia Schiattarella +2
The geometries of surface wave modes are determined by the highly nontrivial interplay of capillarity and wetting effects at the boundaries of their domain. Aside from idealised sc…

Tracking the nonlinear formation of an interfacial wave spectral cascade from one to few to many
Sean M. D. Gregory, Silvia Schiattarella, Vitor S. Barroso +3
A hallmark of far-from-equilibrium systems is the emergence of a spectral cascade, where energy is transferred across length-scales following a simple power law. The universal natu…
