We study a model of fermions interacting with a gauge field and calculate gauge-invariant two-particle Green's functions or response functions. The leading singular contributions from …
Amperean superconductivity is an exotic phenomenon stemming from attractive effective electron-electron interactions (EEEIs) mediated by a transverse gauge field. Originally …

We expand upon an earlier renormalization group analysis of a non-Fermi liquid fixed point that plausibly governs the two-dimensional electron liquid in a magnetic field near filling …
We study instabilities occurring in the electron system whose Fermi surface has flat regions on its opposite sides. Such a Fermi surface resembles Fermi surfaces of some high-T c …

We derive the quantum Boltzmann equation (QBE) of composite fermions at/near the ν= 1/2 state using the nonequilibrium Green's-function technique. The lowest-order perturbative …
We present an analytic theory unraveling the microscopic mechanism of instabilities within interacting D-dimensional Fermi liquid. Our model consists of a D-dimensional electron gas …
We analyze the behavior of an itinerant two-dimensional Fermi system near a charge nematic (n= 2) Pomeranchuk instability in terms of the Landau Fermi-liquid (FL) theory. A …

We show that in the limit of vanishing bare electron mass, and in the presence of particle- hole symmetric disorder (which can be of vanishing strength), the composite-fermion Hall …
