At a conference of quantum physicists (plus a few philosophers and mathematicians) held last year, 64 percent of 33 respondents to a questionnaire declared that Einstein was wrong. Moduli dependence of determinants and Green functions; Lecture 6. A basic knowledge of solid state physics and quantum mechanics at graduate level is assumed. Quantum Fields and Strings, A course for mathematicians, 2 vols. Transverse Susceptibility, and doubts about retarded/advanced Green's Functions, Quantum Physics, 9. This volume shows how the analytic properties in the complex energy plane of the Green's functions of many particle systems account for the physical effects (level, shifts, damping, instabilities) characteristic of interacting systems. It concentrates on general physical principles and, while it does not discuss texts and also to experimentalists who would like a quick view of the subject. On quantum field theory and string theory. It basicly covers: Second Quantization Mean field theory. This is also related to the non-existence of off-shell formulation you mention — the theory cannot be probed locally for very physical reasons. Book "Many-body Quantum theory in condensed matter physics" by K. Meade gives a great explanation of what the wave function actually is (accumulated phase) and what happens when an electron makes a transition to a different energy state. It is shown in books on quantum field theory that that this propagator is simply the Green's function of the Schrödinger equation.
