Low-energy properties of fermions with singular interactions

BL Altshuler, LB Ioffe, AJ Millis - Physical Review B, 1994 - APS
We calculate the fermion Green function and particle-hole susceptibilities for a degenerate
two-dimensional fermion system with a singular gauge interaction. We show that this is a …

Gauge-invariant response functions of fermions coupled to a gauge field

YB Kim, A Furusaki, XG Wen, PA Lee - Physical Review B, 1994 - APS
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 cannot be induced by deep subwavelength cavities in a two-dimensional material

GM Andolina, A De Pasquale, FMD Pellegrino, I Torre… - Physical Review B, 2024 - APS
Amperean superconductivity is an exotic phenomenon stemming from attractive effective
electron-electron interactions (EEEIs) mediated by a transverse gauge field. Originally …

Renormalization group approach to low temperature properties of a non-Fermi liquid metal

C Nayak, F Wilczek - Nuclear Physics B, 1994 - Elsevier
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 …

Parquet solution for a flat Fermi surface

AT Zheleznyak, VM Yakovenko, IE Dzyaloshinskii - Physical Review B, 1997 - APS
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 …

Quantum Boltzmann equation of composite fermions interacting with a gauge field

YB Kim, PA Lee, XG Wen - Physical Review B, 1995 - APS
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 …

Microscopic mechanism of pair-, charge-, and spin-density-wave instabilities in interacting -dimensional Fermi liquids

D Miserev, H Schoeller, J Klinovaja, D Loss - Physical Review B, 2024 - APS
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 …

Composite-fermion Hall conductance at ν=

SA Kivelson, DH Lee, Y Krotov, J Gan - Physical Review B, 1997 - APS
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 …
