Pilot Wave Hydrodynamics



In this episode, Randy and Jim discuss pilot wave hydrodynamics, a physical analogy to quantum mechanics. In it, a small droplet bounces atop a fluid, interacting with its own wave. This allows macroscopic experiments which display many of the properties of quantum mechanics, such as self-interference in a doubles slit experiment. This is equivalent to the de Broglie-Bohm interpretation of quantum mechanics that Jim and Randy talked about in the second episode and a little in the main podcast, as well as the quantum interpretations special (that currently needs re-editing).

Show Notes:

1. The review paper by John W. M. Bush that forms the basis of the discussion.

2. The videos by Veritasium and Smarter Every Day that we refer to in the podcast second episode and just before we recorded this.

3. Both John Bush and Anders Andersen seem to have found no evidence of interference in properly controlled experiments, as described inQuanta Magazine.

Phononics



Randy tells Jim about the emerging field of Phononics: using quantum particles of heat in materials for information processing in advanced materials.

Notes:

The Review Article that we discussed here.

A reasonable YouTube speech on phononics, Prof Ben Eggleton - Phononics, the next wave.
