The stability of matter: is really Maxwell wrong? (part 2).

Click For Summary
SUMMARY

This discussion centers on the limitations of Maxwell's equations in explaining the absence of appreciable electromagnetic emission from matter. The conversation highlights the significance of sinusoidal plane electromagnetic waves and their phase relationships, demonstrating that when these waves are uniformly distributed, the resulting emission is significantly diminished compared to when they are in phase. Key references include the classic paper by Dyson and Lenard and a more recent treatment by Lieb and Seiringer, which provide foundational knowledge necessary for understanding these concepts.

PREREQUISITES
  • Familiarity with Maxwell's equations and their implications in electromagnetism.
  • Understanding of sinusoidal plane electromagnetic waves and their phase relationships.
  • Knowledge of phasor methods in wave analysis.
  • Background in advanced theoretical physics, particularly in classical electrodynamics.
NEXT STEPS
  • Study the classic paper by Dyson and Lenard on electromagnetic theory.
  • Review the recent treatment by Lieb and Seiringer for contemporary insights.
  • Learn about the implications of phase relationships in wave interference.
  • Explore advanced topics in classical electrodynamics to deepen understanding of matter stability.
USEFUL FOR

This discussion is beneficial for theoretical physicists, graduate students in physics, and researchers interested in the foundations of electromagnetism and the stability of matter.

In a previous message I have tried to show that electrical systems exist which do not generate electromagnetic waves with appreciable energy even if such systems have parts in accelerated motion.
Now I add a further example by which the meaning of what I tried to say becomes clearer.
The problem is the following: it is required to investigate the character of the electromagnetic emission resulting from a sum of a great, very great number of sinusoidal plane electromagnetic waves (with same polarization) with same amplitude, same frequency and phase uniformly distributed on the whole 360 degrees angle.
It is not difficult to imagine a physical example of source whose emission is as above described.
This time calculations were made and the result is more than clear: the resulting emission is infinitely smaller in comparison to that we have when all the signals are in phase.
The fact is quite intuitive if we help us with the method of phasors.
So my question is always the same: are we really sure that Maxwell cannot explain the absence of appreciable electromagnetic emission from matter?
Are we really sure that classical theory cannot explain the stability of matter?
I have some doubt.

Yes.

Yes.
 
Dear Drakkith,
thank you for your response, surely clear and perhaps a little too concise.

Then you have evidently not acquired the level of background knowledge that would be expected if you are going to start an "A" level (graduate level) thread on this topic. You should certainly be familiar with the classic paper on the topic by Dyson and Lenard:

A more recent treatment is Lieb and Seiringer:

No, his answer was exactly right for an "A" level thread: the conciseness is a way of conveying to you that you should already have enough background knowledge to fill in the details for yourself. If you don't, you need to fix that before starting another thread on this topic.
