Derivation of Line Shape Function in the Optical Conductivity by a New Diagram Method
A new diagram method for the line shape function in the optical conductivity formula is introduced and the result obtained applying the method to an electron-phonon system is compared with that derived using the projection-reduction method. The result satisfies the population criterion, which states...
