Rotational superradiance was predicted theoretically decades ago, and is chiefly responsible for a number of important effects and phenomenology in black-hole physics. However, rotational superradiance has never been observed experimentally. Here, wi... Read More about Detecting rotational superradiance in fluid laboratories.

On the observation of nonclassical excitations in Bose–Einstein condensates (2016)

In the recent experimental and theoretical literature well-established nonclassicality criteria from the field of quantum optics have been directly applied to the case of excitations in matter-waves. Among these are violations of Cauchy–Schwarz inequ... Read More about On the observation of nonclassical excitations in Bose–Einstein condensates.

The imprint of the analogue Hawking effect in subcritical flows (2016)
Journal Article

We study the propagation of low-frequency shallow water waves on a one-dimensional flow of varying depth. When taking into account dispersive effects, the linear propagation of long-wavelength modes on uneven bottoms excites new solutions of the disp...

Extrinsic curvature in two-dimensional causal dynamical triangulation (2016)
Journal Article

Causal dynamical triangulation (CDT) is a nonperturbative quantization of general relativity. Hořava-Lifshitz gravity, on the other hand, modifies general relativity to allow for perturbative quantization. Past work has given rise to the speculation...
