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…
Digital holographic imaging for free surfaces of superfluid helium
Vitor S. Barroso, Patrik Švančara, Chris Goodwin +9
Visualising the free surface of superfluid helium offers a rare opportunity to explore wave dynamics in the limit of vanishing viscosity. Such measurements are nonetheless challeng…
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…
On the semiclassical and quantum picture of the Bianchi I polymer dynamics
Eleonora Giovannetti, Giovanni Montani, Silvia Schiattarella
We analyze the Bianchi I cosmology in the presence of a massless scalar field and describe its dynamics via a semiclassical and quantum polymer approach. We investigate the morphol…
Semiclassical and quantum features of the Bianchi I cosmology in the polymer representation
E. Giovannetti, G. Montani, S. Schiattarella
We analyze the Bianchi I cosmology in the presence of a massless scalar field and describe its dynamics via a semiclassical and quantum polymer approach. We study the morphology of…
