THE INTERACTION FIELD AMPLITUDE. & Walecka, Quantum Theory of Many-Particle Systems Hedin, L. In the quantum theory for a many-body system, the absolute square of the amplitude. Particle', it is the interaction relation, holistically, that is elementary here. As often expressed, the axioms of quantum mechanics (see Sec. The central question concerns quantum measurement. 2.1 of my notes here) distinguish two different ways for a quantum state to change. I have called it: 'elementary interaction.' 3. Texts and monographs on many-body theory: Doniach, S. & Sondheimer, Greens Functions for Solid State Physicists Fetter, A. Thermodynamics, the crown jewel of 19th-century physics, concerns systems with many particles. Advanced Quantum Mechanics, the second volume on quantum mechanics by Franz Schwabl, discusses nonrelativistic multi-particle systems, relativistic wave equations and relativistic quantum fields. Quantum mechanics, developed in the 20th century, works best when applied to just a few.
