Insulating ground state and 2-k magnetic structure of candidate Weyl Hydrogen atom KMn(AsO)
Keith M. Taddei, Kulugammana G. S. Ranmohotti, Duminda S. Liurukara +6
The ideal Weyl 'Hydrogen-atom' semi-metal exhibits only a single pair of Weyl nodes and no other trivial states at the Fermi energy. Such a material would be a panacea in the study…
Zig-Zag magnetic order and potential Kitaev interactions in the spin-1 honeycomb lattice KNiAsO
K. M. Taddei, V. O. Garlea, A. M. Samarakoon +6
Despite the exciting implications of the Kitaev spin-Hamiltonian, finding and confirming the quantum spin liquid state has proven incredibly difficult. Recently the applicability o…
Single pair of Weyl nodes in the spin-canted structure of EuCdAs
K. M. Taddei, L. Yin, L. D. Sanjeewa +6
Time reversal symmetry breaking Weyl semimetals are unique among Weyl materials in allowing the minimal number of Weyl points thus offering the clearest signatures of the associate…
Evidence of Ba substitution induced spin-canting in the magnetic Weyl semimetal EuCdAs
L. D. Sanjeewa, J. Xing, K. M. Taddei +4
Recently EuCdAs was predicted to be a magnetic Weyl semi-metal with a lone pair of Weyl nodes generated by A-type antiferromagnetism and protected by a rotational symmetry.…
Acoustic impedance and interface phonon scattering in BiTe and other semiconducting materials
Xin Chen, David Parker, David J. Singh
We present first principles calculations of the phonon dispersions of Bi2Te3 and discuss these in relation to the acoustic phonon interface scattering in ceramics. The phonon dispe…
Neutron scattering and muSR investigations of the spin liquid state with quenched disorder in LuCuGaO4
S Calder, SR Giblin, DR Parker +5
LuCuGaO4 has magnetic Cu2+ and diamagnetic Ga3+ ions distributed on a triangular bilayer and is suggested to undergo a spin-glass transition with T_g approximately 0.4 K. Using muS…
Incommensurate spin resonance in URu2Si2
A. V. Balatsky, A. Chantis, Hari P. Dahal +2
We focus on inelastic neutron scattering in and argue that observed gap in the fermion spectrum naturally leads to the spin feature observed at energies $ω_{res} = 4-6…
