Title:
Hydrodynamic quantum analogs
Abstract:
In 2005, it was 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.
