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…
Inverse energy transfer in three-dimensional quantum vortex flows
Piotr Z. Stasiak, Andrew Baggaley, Carlo. F. Barenghi +2
Vortex reconnections play a fundamental role in fluids.They increase the complexity of flow and develop small-scale motions.In this work, we report that in superfluids, they can al…
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…
Quantum vortices leave a macroscopic signature in the normal fluid
Luca Galantucci, Giorgio Krstulovic, Carlo F Barenghi
Recent work has highlighted the remarkable properties of quantum turbulence in superfluid helium II, consisting of a disordered tangle of quantised vortex lines which interact with…
Experimental and theoretical evidence of universality in superfluid vortex reconnections
Piotr Z. Stasiak, Yiming Xing, Yousef Alihosseini +5
The minimum separation between reconnecting vortices in fluids and superfluids obeys a universal scaling law with respect to time. The pre-reconnection and the post-reconnection pr…
Vortex Avalanches and Collective Motion in Neutron Stars
I-Kang Liu, Andrew W. Baggaley, Carlo F. Barenghi +1
We simulate the dynamics of about 600 quantum vortices in a spinning-down cylindrical container using a Gross--Pitaevskii model. For the first time, we find convincing spatial-temp…
