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…

Fermi-Bose Correspondence at Finite Temperature
Girish S. Setlur
The correspondence between fermi-sea/bose-condensate displacements and the number-conserving product of two fermi/bose fields is generalised to finite temperatures. It is shown tha…
