Textbooks and references
Relativistic Quantum Mechanics
A classic and useful textbook is:
- Bjorken and Drell, "Relativistic Quantum Mechanics" (Mc Graw-Hill)
Relativistic wave equations (Klein-Gordon, Dirac, Maxwell-Proca)
can be studied on QFT textbooks, such as
- M. Srednicki, "Quantum Field Theory" (free on
http://www.physics.ucsb.edu/~mark/qft.html) (CUP);
- C. Itzykson, J.B. Zuber, "Quantum Field Theory" (Dover);
- S. Weinberg, "The Quantum Theory of Fields" (CUP).
Useful references for the various types of Green functions
(retarded, advanced, etc.) are:
- Itzykson, Zuber, "Quantum Field Theory" - pag. 32-36
- B. DeWitt, "Dynamical Theory of Groups and Fields - pag. 30-34
- de Wit, Smith, "Fields in Particle Theory" - pag. 39-50
Path Integrals
Same textbooks are:
- Feynman and Hibbs, "Quantum Mechanics and Path Integrals"
- Schulman L., "Techniques and Applications of Path Integration"
