Expressing the Field Operator in Terms of Currents and Densities
Girish S. Setlur
A formula is written down for the annhilation operator(bose or fermi) in terms of the corresponding observable bilinears namely currents and densities. The Fock space representatio…
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…
Exact Momentum Distribution of a Fermi Gas in One Dimension
Girish S. Setlur
We introduce an exactly solvable model of a fermi gas in one dimension and compute the momentum distribution exactly. This is based on a generalisation of the ideas of bosonization…
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…
Exact Dynamical Structure Factor of a Bose Liquid
Girish S. Setlur
Based on ideas introduced in a previous preprint cond-mat/9701206 we propose an exactly solvable model of bosons interacting amongst themselves via a Van-der Waal-like repulsive in…
Expressing Products of Fermi Fields in terms of Fermi Sea Displacements
Girish S. Setlur
An attempt is made to generalise the ideas introduced by Haldane and others regarding Bosonizing the Fermi surface. The present attempt involves introduction of Bose fields that co…
