Kondo singlet from ferromagnetic coupling: an analog of Anderson-Morel superconductivity in the magnetic channel
Ewan Scott, Yaqi Chen, Michael Turaev +4
We consider magnetic impurities coupled to a conduction sea via a fully isotropic ferromagnetic spin-exchange term, the strength of which depends on the conduction-electron modes i…

Non-Fermi liquid induced by U(1) gauge field interactions: a functional renormalization group analysis
Thomas P. Sheerin, Chris A. Hooley
We study the non-Fermi-liquid state formed by an isotropic, degenerate Fermi gas in two spatial dimensions interacting with a U(1) gauge field. Our calculation uses the functional…

Magnetic Order and Magnetic Excitations in FeTe: How Good is a Short-Range Heisenberg Model?
Joe Marshall, Chris A. Hooley
We revisit the fitting of the Fang-Bernevig-Hu model [Europhys. Lett. 86, 67005 (2009)] to inelastic neutron scattering data carried out by Lipscombe et al. [Phys. Rev. Lett. 106,…
