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…

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…

Stability of quantised vortices in two-component condensates

Sam Patrick, Ansh Gupta, Ruth Gregory +1

Multiply quantised vortices (MQVs) within single component Bose-Einstein condensates are unstable and decay rapidly. We show that MQVs can be stabilised by adding a small number of…

Imperfect draining vortex as analogue extreme compact object

Theo Torres, Sam Patrick, Ruth Gregory

Motivated by recent experimental progress, we study scalar wave propagation over an imperfect draining vortex, which can serve as an analogue for rotating and non-rotating extreme…

Quantum vortex instability and black hole superradiance

Sam Patrick, August Geelmuyden, Sebastian Erne +2

Vortices and black holes set the scene for many interesting dynamical processes in physics. Here, we study the dynamical instability of quantised vortices and rotational superradia…

On the Formation and Interaction of Multiple Supermassive Stars in Cosmological Flows

Tyrone E. Woods, Samuel Patrick, Daniel J. Whalen +1

Supermassive primordial stars with masses exceeding that form in atomically cooled halos are the leading candidates for the origin of high-redshift quasars wi…
