Derivation of the one-particle Green's function?

Click For Summary
SUMMARY

The discussion centers on the search for a comprehensive reference on the derivation of the single-particle Green's function, specifically within the context of quantum mechanics. The user expresses disappointment that key texts such as Sakurai and Ashcroft do not cover the spectral representation of this function. Recommendations include Bjorken and Drell, Volume II, Appendix C, which provides a thorough treatment of the resolvent of the single-particle Hamiltonian and the Green's functions for the Klein-Gordon and Dirac equations.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly single-particle Hamiltonians.
  • Familiarity with Green's functions and their applications in quantum field theory.
  • Knowledge of bracket notation used in quantum mechanics.
  • Basic concepts of spectral representation in quantum systems.
NEXT STEPS
  • Study the resolvent operator in quantum mechanics.
  • Explore the derivation of Green's functions in quantum field theory.
  • Read Bjorken and Drell, Volume II, focusing on Appendix C for detailed examples.
  • Investigate the applications of Green's functions in the Klein-Gordon and Dirac equations.
USEFUL FOR

Quantum mechanics students, theoretical physicists, and researchers interested in advanced topics related to Green's functions and their applications in quantum field theory.

Hello,

I am looking for a good reference book that has a detailed derivation of the single particle Green's function. I expected this to be in Sakurai but it's not. I couldn't find the spectral representation of this simple function in Ashcroft or any other solid state book either. Jackson has plenty on Green's functions for charged systems but I'd like to use a quantum text with bracket notation of some kind.

Basically I am looking for some thorough treatment of the resolvent of the single particle Hamiltonian and the representations of the Green's function. What text would you recommend?

Assuming you mean the Green's functions for the Klein-Gordon equation and the Dirac equation, a good treatment can be found in Bjorken and Drell vol II, Appendix C.
