Discussion Overview

The discussion revolves around the semiclassical approach to calculating the emission spectrum, specifically focusing on the emission of photons by a two-level system interacting with a monochromatic electromagnetic wave. Participants explore references and resources related to this topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant inquires about resources for calculating the emission spectrum using the semiclassical approach.
  • Another participant humorously questions the type of emission being discussed, suggesting various interpretations including X-rays and secondary electrons.
  • A participant clarifies that they are interested in the emission of photons, particularly in the context of a two-level system interacting with a monochromatic electromagnetic wave.
  • There is a humorous reference to the classical approach to "emission of money," while also mentioning the standard reference for the semiclassical approach: E.T. Jaynes and F.W. Cummings' work on the Jaynes-Cummings model.
  • Participants mention that overview articles on the Jaynes-Cummings model may be available for free or on ArXiv, suggesting that a quick search could yield useful resources.
  • One participant expresses gratitude for the suggestions provided, indicating that they found the information helpful.

Areas of Agreement / Disagreement

Participants generally agree on the interest in the semiclassical approach to photon emission, but there is no consensus on the specifics of the emission types or the applicability of the semiclassical model to different contexts.

Contextual Notes

There are limitations regarding the clarity of the specific emission type being discussed and the assumptions underlying the semiclassical approach. The discussion also reflects a mix of serious inquiry and humor, which may affect the interpretation of contributions.

Who May Find This Useful

This discussion may be useful for those interested in the semiclassical approach to quantum mechanics, particularly in the context of photon emission and the Jaynes-Cummings model.

Where can i find something on the calculation of the emission spectrum with the semiclassical approach?

Thanks

Emission of what? X-ray? Secondary electrons? Twinkies?

Zz.
 
Sorry, mmmm money?...If money is not possible, my second choice is emission of photons by a system. For example a two level system interacting with a monochromatic E.M. wave

I am not sure about the semiclassical approach, but the classical approach to emission of money is working. At least for spontaneous emission. If you are interested in stimulated emission you might have to ask someone who was involved with Lehman Brothers or some related bank.

The standard reference is: E.T. Jaynes, F.W. Cummings (1963). "Comparison of quantum and semiclassical radiation theories with application to the beam maser". Proc. IEEE 51 (1): 89–109. DOI:10.1109/PROC.1963.1664.

If you do not have access to that article, there are also plenty of overview articles on what has been termed the Jaynes-Cummings model. (two-level atom interacting with a quantized cavity mode). Some of them should also be available for free or on the ArXiv. A quick google search should find you one of these.
 
Please excuse me for taking so long to answer, i want to thanks for the suggestion it has been helpful! :)

Also for money stimulated emission!
