Digital holographic imaging for free surfaces of superfluid helium
Vitor S. Barroso, Patrik Å vanÄara, 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 Å vanÄara +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…
Spectroscopy of analogue black holes using simulation-based inference
Leonardo Solidoro, Sebastian H. Völkel, Silke Weinfurtner
The emergence of precision gravity simulators in quantum and fluid systems is opening new avenues for probing curved-spacetime physics and black-hole phenomenology under controlled…
When is a sloshing vortex an analogue black hole bomb?
Sam Patrick, Leonardo Solidoro, MaurÃcio 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…
On the origin of quasinormal modes in semi-open systems
Leonardo Solidoro, Sam Patrick, Ruth Gregory +1
Astrophysical black holes are open systems which, when perturbed, radiate quasi-normal modes (QNMs) to infinity. By contrast, laboratory analogues are necessarily finite-sized, pre…
Quasinormal modes in Lorentz violating black hole analogues
Sam Patrick, Leonardo Solidoro
Analogue models of black holes typically have collective excitations with a dispersion relation that breaks the effective Lorentz symmetry at high energy. We investigate the conseq…
