Journal of Fluid Mechanics Webinar Series: John Bush, MIT

The Leeds Institute for Fluid Dynamics is delighted to partner with the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, the UK Fluids Network, and the Journal of Fluid Mechanics to deliver a regular webinar series on fluids-related topics.

Our second seminar will take place at 4:00pm BST on Friday 15th May, 2020.

Speaker: John W. M. Bush, MIT, USA

Date/Time: Friday 15th May, 2020. 4:00pm BST/11am EDT

Title: Pilot-wave hydrodynamics, hydrodynamic quantum analogs, and hydrodynamic quantum field theory

Abstract: In 2005, Yves Couder and Emmanuel Fort discovered that droplets walking on a vibrating fluid bath exhibit several features previously thought to be exclusive to the microscopic, quantum realm. These walking droplets propel themselves by virtue of a resonant interaction with their own wave field, and so represent the first macroscopic realization of a pilot-wave system of the form proposed for microscopic quantum dynamics by Louis de Broglie in the 1920s. New experimental and theoretical results allow us to rationalize the emergence of quantum-like behavior in this hydrodynamic pilot-wave system in a number of settings, and explore its potential and limitations as a quantum analog. A new, trajectory-based description of quantumdynamics, informed by the hydrodynamic system, is proposed and explored.

The webinar will take place on Zoom. Register for this event and the whole series here.
