Speaker: John Bush, MIT
Subject: Hydrodynamic quantum analogs

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 monochromatic wavefield, and 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.

Subject: Discussions Over a Beer: Bohr, Einstein, Bell, and all that

The Bohr-Einstein debate about the foundations of quantum mechanics is something physicists tend to think of as the sort of thing you might discuss over a beer after you’ve spent the day doing real physics. Following John Bell’s seminal 1964 paper on nonlocality, there’s a new game in town influenced by developments in quantum information. I’ll discuss the significance of this new wave in quantum foundations for the dispute that separated Bohr and Einstein. (Bring your own beer.)
