SUMMARY

The discussion centers on whether a stationary charge in a gravitational field emits radiation, referencing the equivalence principle (EP) and Larmor's formula. Participants debate the application of the EP to charged particles, with some asserting it does not apply, while others cite research by Amos Harpaz and Noam Soker (1999) that suggests it does. The conversation also touches on the complexities of measuring radiation from such charges and the implications for conservation of energy. Key references include arXiv papers on electromagnetic self-force and the local nature of the EP.

PREREQUISITES
  • Understanding of the equivalence principle in general relativity
  • Familiarity with Larmor's formula for radiation from accelerated charges
  • Knowledge of electromagnetic self-force concepts
  • Basic principles of radiation detection methods
NEXT STEPS
  • Study the implications of the equivalence principle on charged particles
  • Review the paper "Radiation from a Charge in a Gravitational Field" by Harpaz and Soker
  • Examine the concept of electromagnetic self-force in detail
  • Learn about experimental methods for detecting radiation from stationary charges
USEFUL FOR

Physicists, researchers in general relativity, and anyone interested in the intersection of electromagnetism and gravitational theory.

The instructor also recommends as excellent reading on this subject: G. Greenstein and A.G. Zajonc, “The Quantum Challenge” (Jones and Bartlett Publishers, 2005).

This is the same reference I gave in post #51. The reference states that quantization of the electromagnetic field is not necessary to explain the photoelectric effect (there's a caveat to this, but it's not relevant at this point).

I've started a thread about this in the quantum physics forum. The problem with the Scully-Lamb model is that it violates conservation of energy.

I wasn't able to access anything via the link in your #51, but I was able to find the book on amazon, which let me see certain pages. However, I was unable to see the page where they give their reference [1]. Do you have the actual book, and is reference [1] the internal report that's been floating around? I was able to access the pages where they present the idea, and it's basically just a summary of the internal report. They ignore the same issue Scully and Lamb ignore, which is that the hybrid model violates conservation of energy.

I haven't got the book, was browsing at Borders some time ago which is when I came across their discussion.

It's funny trying to access this information through "keyholes" like amazon and google books. Although I couldn't access the book through google books at home, I am able to access it through google books here at work. Right after the section on the photoelectric effect, they have a section called "anticoincidences," which makes essentially the same point I'm making. Anyway, the Quantum Physics forum is really the right place to continue this discussion.
