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…
When is a sloshing vortex an analogue black hole bomb?
Sam Patrick, Leonardo Solidoro, Maurício Richartz +4
Draining vortices provide a powerful platform for simulating black hole phenomena in tabletop experiments. In realistic fluid systems confined within a finite container, low-freque…
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…
Black-hole spectroscopy from a giant quantum vortex
Pietro Smaniotto, Leonardo Solidoro, Patrik Švančara +5
Black-hole spectroscopy aims to infer the fundamental properties of black holes by analysing the spectrum of gravitational waves emitted as they settle into equilibrium. These reso…
