Elementary Excitations at Magnetic Surfaces and Their Spin Dependence
(AMER PHYSICAL SOC, 2011)
The elementary surface excitations are studied by spin-polarized electron energy loss spectroscopy on a prototype oxide surface [an oxygen passivated Fe(001)-p(1 x 1) surface], where the various excitations coexist. For ...
Prediction and control of spin polarization in a Weyl semimetallic phase of BiSb
(2016)
By means of first-principle calculations, we report a stoichiometric crystal structure of BiSb with broken space-inversion symmetry. This structure is insulating in bulk and has nontrivial band topology. We observe a ...
Symmetry-protected metallic and topological phases in penta-materials
(2019)
We analyze the symmetry and topological features of a family of materials closely related to penta-graphene, derived from it by adsorption or substitution of different atoms. Our description is based on a novel approach, ...
Resonant electron tunneling spectroscopy of antibonding states in a Dirac semimetal
(2018-06-12)
Recently, it was shown both theoretically and experimentally that certain three-dimensional (3D) materials have Dirac points in the Brillouin zone, thus being 3D analogs of graphene. Moreover, it was suggested that under ...
Chiral Spin-Orbital Liquids with Nodal Lines
(2016-07-01)
Strongly correlated materials with strong spin-orbit coupling hold promise for realizing topological phases with fractionalized excitations. Here, we propose a chiral spin-orbital liquid as a stable phase of a realistic ...
A model of the Fermi surface for antiferromagnetic europium metal
(1973)
Energy gaps near the Fermi surface arising from magnetic Brillouin zone effects must be taken into account in order to understand the antiferromagnetism of europium metal. © 1973 Pergamon Press.
