Rotating Curved Spacetime Signatures from a Giant Quantum Vortex
Patrik Å vanÄara, 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…
Quasinormal Modes of Optical Solitons
Christopher Burgess, Sam Patrick, Theo Torres +2
Quasinormal modes (QNMs) are essential for understanding the stability and resonances of open systems, with increasing prominence in black hole physics. We present here the first s…
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…
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…
Quantum vortex stability in draining fluid flows
Sam Patrick
Quantum vortices with more than a single circulation quantum are usually unstable and decay into clusters of smaller vortices. One way to prevent the decay is to place the vortex a…
Backreaction in an analogue black hole experiment
Sam Patrick, Harry Goodhew, Cisco Gooding +1
In general relativity, the interaction between a black hole and the fields around it (a process known as backreaction) proceeds via the evolution of the black holes mass and angula…
