Texts on Quantum Fields without Maxwell's Equations

Click For Summary
SUMMARY

This discussion centers on the exploration of quantum electromagnetism without the application of Maxwell's equations. Participants express skepticism regarding the efficacy of such texts, particularly highlighting Steven Weinberg's "The Quantum Theory of Fields," which minimally references Maxwell's equations. Eugene mentions Carver A. Mead's approach, which utilizes a four-vector potential in conjunction with quantum theory, emphasizing the clarity provided by superconducting inductors. The consensus leans towards the belief that excluding Maxwell's equations may hinder understanding.

PREREQUISITES
  • Understanding of quantum electromagnetism principles
  • Familiarity with Maxwell's equations
  • Knowledge of four-vector potential in physics
  • Basic concepts of superconductivity and inductors
NEXT STEPS
  • Research the implications of excluding Maxwell's equations in quantum field theory
  • Study Steven Weinberg's "The Quantum Theory of Fields" for insights on modern quantum theories
  • Explore Carver A. Mead's four-vector potential approach in detail
  • Investigate the role of superconducting inductors in quantum electromagnetism
USEFUL FOR

Physicists, students of quantum mechanics, and researchers interested in advanced theoretical physics, particularly those examining the foundations of quantum electromagnetism.

Hi

I would like to know what your thoughts are on books that make an attempt to discuss quantum electromagnetism without using any of Maxwell's equations. I came across a text written by an author who decided not to use Maxwell's equations because Maxwell and others "didn't have access" to modern experiments. Personally, I think it's probably a bad idea, but I want as many people to post in here what they think. Thanks :)

Carver A Mead uses a four-vector potential approach combined with quantum theory in the same way.

I particularly like his use of superconducting inductors to illustrate points that become obvious in retrospect.
