Momentum Distribution of a Weakly Coupled Fermi Gas
Girish S. Setlur
We apply the sea-boson method to compute the momentum distribution of a spinless continuum Fermi gas in two space dimensions with short-range repulsive interactions. We find that t…

Quenched Disorder From Sea-Bosons
Girish S. Setlur
The degenerate Fermi gas coupled to a random potential is used to study metal-insulator transitions in various dimensions. We first recast the problem in the sea-boson language tha…

A.C. Conductivity of a Disordered Metal
Girish S. Setlur
The degenerate free Fermi gas coupled to a random potential is used to compute a.c. conductivity in various dimensions. We first formally diagonalise the hamiltonian using an appro…
