A Hydrodynamic Approach to Superconductivity
Girish S. Setlur
Recently Tsai et.al. (cond-mat/0406174) have used the renormalization group approach to study strong coupling superconductors without assuming a broken symmetry phase. We use the h…
Towards a Hydrodynamic Theory of Infinite Neutral Nonrelativistic Matter
Girish S. Setlur
We recast the problem of infinite neutral nonrelativistic matter interacting via U(1) gauge fields in the hydrodynamic language. We treat the nuclei as being spinless bosons for si…
Sea-Boson Analysis of the Infinite-U Hubbard Model
Girish S. Setlur
By expanding the projection operator in powers of the density fluctuations, we conjecture a hamiltonian purely quadratic in the sea-bosons that reproduces the right spin and charge…
Hydrodynamic Formulation of the Hubbard Model
Girish S. Setlur
In this article, we show how to recast the Hubbard model in one dimension in a hydrodynamic language and use the path integral approach to compute the one-particle Green function.…
A Novel Non-Fermi Liquid Ground State in One Dimension
Girish S. Setlur, HRI
We propose a new non-Fermi liquid ground state in one dimension that is not of the Luttinger type. It is the ground state of fermions interacting via a long range repulsive interac…
Quantum Hydrodynamics of Fermi Fluids
Girish S. Setlur
It is shown that gauge theories with fermions are most naturally studied via a polar decomposition of the field variable. This is the fermionic analog of the preprint cond-mat/0210…
