The Unruh Effect

Randy and Jim about the perspectival nature of quanta, the Unruh effect, which says that for highly accelerated systems, additional particles and temperature will be seen.

  • Leonhardt, U. and Philbin, T., Geometry and Light: The Science of Invisibility (2010). This is a textbook on using the methods of general relativity in the behavior of light in nonlinear materials that I quite enjoyed when I read it. It starts off with an old favorite, variational principles, like Fermat's principle of least time, and passes through a short course on differential geometry, before mixing light and geometry with Maxwell's equations. After that, he discusses optical analogs of black holes, the optical Aharonov-Bohm effect, and other topics -- like "cloaking at a distance:" invisibility! It has full color illustrations, which helps with differential geometry, and better, it's a Dover book so its cheap! [Amazon].

  1. There's been a lot of talk about The Unruh Effect in the last couple of years with the advent of the Quantized Inertia theory by McCullough.
    Was glad to see this pop up, nothing since January had me worried you guys had abandoned this podcast after I had just found it :)

    1. Nope, just got really busy at work. We're trying to get more recorded right now.
