Particlelike solutions of the Einstein-Dirac-Higgs equations: ground, excited, and many-fermion states
Reinosuke Kusano, Keith Horne, Peter E. D. Leith +2
We present an extended study of the gravitationally localized soliton-like solutions to the minimally-coupled Einstein-Dirac-Higgs equations, embedded in asymptotically Minkowski s…
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…
'Stealth' singularities from self-gravitating fermions
Peter E. D. Leith, Chris A. Hooley, Keith Horne +1
We present a new analytic solution to the Einstein-Dirac equations formulated by Finster, Smoller, and Yau [Phys. Rev. D 59, 104020 (1999)] to describe the stationary states of a p…
Classically Bound and Quantum Quasi-Bound States of an Electron on a Plane Adjacent to a Magnetic Monopole
J. Martin, A. Baskerville, V. L. Campo +6
In three-dimensional space an electron moving in the field of a magnetic monopole has no bound states. In this paper we explore the physics when the electron is restricted to a two…
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,…
