,Green’s Functions at Zero Temperature,ugh they are often at low temperature. Many quantities are not very sensitive to temperature, particularly at low temperature. Zero temperature calculations are useful even for describing real systems. Furthermore, the zero temperature property of a system is an important conceptual quantity—the gro作者: 有機體 時間: 2025-3-22 03:31
Nonzero Temperatures,should be done at nonzero temperatures too. It is often unnecessary if the temperature is small compared to other energies in the problem. But often temperature is important, and here it will be incorporated into Green’s functions. The nonzero temperature formalism was originated by Matsubara (1955)作者: 有角 時間: 2025-3-22 08:17

Optical Properties of Solids,ron system does not absorb light at all, so that its optical properties are uninteresting. The ability of the nearly free-particle system to absorb light is due to its imperfections or deviations from homogeneity. If these effects are small, then so is the light absorption.
