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…
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…
Optical lever for broadband detection of fluid interface fluctuations
Sreelekshmi C. Ajithkumar, Vitor S. Barroso, Patrik Švančara +2
We exploit the optical lever principle to detect minute fluctuations of a liquid-air interface. Waves propagating on the interface deflect a specularly reflected laser beam, induci…
Rotating Curved Spacetime Signatures from a Giant Quantum Vortex
Patrik Švančara, Pietro Smaniotto, Leonardo Solidoro +5
Gravity simulators are laboratory systems where small excitations like sound or surface waves behave as fields propagating on a curved spacetime geometry. The analogy between gravi…
