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.
1. The papers we read for this program:
- Crispino, L.C.B, A. Higuchi, and G.E.A. Matsas, "The Unruh Effect and It's Applications." Rev. Mod. Phys. 80, 787 (2008). [arXiv]
- Akhmedov, E.T. and D. Singleton, "On the physical meaning of the Unruh effect." JETP Letters 86, 615 (2008). [arXiv]
2. Popular articles discussed on the program:
- Ingrid Fadelli, "Testing Hawking radiation in laboratory black hole analogues." Phys.org (20019).
3. Related Episodes of Physics Frontiers:
- Physics Frontiers 31: The Parameterized Post-Newtonian Framework.
- Physics Frontiers 9: f(R) Theories of Gravity.
4. Books discussed on this podcast:
- 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].

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.ReplyDelete
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 :)
Nope, just got really busy at work. We're trying to get more recorded right now.Delete
