Journal Article
Cardoso, V., Coutant, A., Richartz, M., & Weinfurtner, S. (2016). Detecting rotational superradiance in fluid laboratories. Physical Review Letters, 117(27), Article 271101. https://doi.org/10.1103/PhysRevLett.117.271101

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.

The imprint of the analogue Hawking effect in subcritical flows (2016)
Journal Article
Coutant, A., & Weinfurtner, S. (2016). The imprint of the analogue Hawking effect in subcritical flows. Physical Review D, 94(6), Article 064026. https://doi.org/10.1103/PhysRevD.94.064026

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...
