SUMMARY:Hydrodynamic Black Holes - Silke Weinfurtner\, U. Nottingham
DTSTART:20230224T160000Z

CONTACT:Prof. Jerome Neufeld
DESCRIPTION:We will discuss experimental results studying the wave-vortex 
 interaction arising from rotating fluid and superfluid flows. The dynamica
 l equation describing the wave-vortex interaction can be mapped to scalar 
 fields propagating on an effective rotating black hole. This opens the pos
 sibility of studying a variety of rotating black hole processes in hydrody
 namic systems. I will summarise our experimental efforts resulting in the 
 detection of geodesic motion\, quasi-normal modes and superradiance in nor
 mal fluids at room temperature and pressure. I will end by introducing our
  new experimental system and first results obtained within. Our new approa
 ch is based on superfluid optomechanics\, allowing us to study rotating bl
 ack hole effects in the quantum domain.
