Physics/Fields Colloquium 2011-2012

Organizing Committee:
Mary Pugh (Toronto) and  Stephen Morris (Dept. of Physics, University of Toronto)

The goal of the Physics/Fields Colloquium is to feature scientists whose work is of interest to both the physics and the mathematical science community. The series has been running since the Spring of 2007.
Usually there is one speaker per semester. Each speaker gives a primary, general talk in the regular physics colloquium venue and, whenever possible, a second, more specialised talk at the Fields Institute.

Previous speakers have been Andy Ruina (March 2011), Eitan Grinspun (November 2010), Jane Wang (March 2010), Carson Chow (December 2009), Ehud Meron (March 2009),
Andrea Liu (Nov 2008), Jun Zhang (October 2007), and Phil Holmes (March 2007).

Wave-particle duality at the macroscopic scale

It is usually assumed that the quantum wave-particle duality can have no counterpart in classical physics. Is this entirely true? We came across this question when we found that a droplet bouncing on a vibrated bath can couple to the surface wave it excites and become propagative. Through several experiments on this classical system we address a general question. How can a continuous and spatially extended wave have a common dynamics with a localized and discrete droplet? Surprisingly some quantum-like behaviors emerge; a form of uncertainty and a form of quantization are observed. I will show that both properties are related to the "path memory" contained in the wave field. The relation of this experiment with the pilot wave models proposed by de Broglie and by Bohm for quantum mechanics will be discussed.
