Exact Optical Dielectric Function of a Nearly Homogeneous Solid
Girish S. Setlur, Yia-Chung Chang
Based on an exactly solvable model of a nearly homogeneous solid (jellium+phonons), we compute the optical dielectric function exactly at zero temperature in any number of spatial…

Single-Particle Green Functions in Exactly Solvable Models of Bose and Fermi Liquids
Girish S. Setlur, Yia-Chung Chang
Based on a class of exactly solvable models of interacting bose and fermi liquids, we compute the single-particle propagators of these systems exactly for all wavelengths and energ…
