High-temperature quantum coherence of spinons in a rare-earth spin chain
Lazar L. Kish, Andreas Weichselbaum, Daniel M. Pajerowski +6
Conventional wisdom dictates that quantum effects become unimportant at high temperatures. In magnets, when the thermal energy exceeds interactions between atomic magnetic moments,…
Coupling of magnetism and Dirac fermions in YbMnSb2
Xiao Hu, Aashish Sapkota, Zhixiang Hu +5
We report inelastic neutron scattering measurements of magnetic excitations in YbMnSb2, a low-carrier-density Dirac semimetal in which the antiferromagnetic Mn layers are interleav…
Efficient loading of reduced data ensembles produced at ORNL SNS/HFIR neutron time-of-flight facilities
William F Godoy, Andrei T Savici, Steven E Hahn +1
We present algorithmic improvements to the loading operations of certain reduced data ensembles produced from neutron scattering experiments at Oak Ridge National Laboratory (ORNL)…
On-the-fly Autonomous Control of Neutron Diffraction via Physics-Informed Bayesian Active Learning
Austin McDannald, Matthias Frontzek, Andrei T. Savici +8
Neutron scattering is a unique and versatile characterization technique for probing the magnetic structure and dynamics of materials. However, instruments at neutron scattering fac…
Magnetic, superconducting, and topological surface states on FeTeSe
Yangmu Li, Nader Zaki, Vasile O. Garlea +9
The idea of employing non-Abelian statistics for error-free quantum computing ignited interest in recent reports of topological surface superconductivity and Majorana zero modes (M…
Signatures of coupling between spin waves and Dirac fermions in YbMnBi
A. Sapkota, L. Classen, M. B. Stone +6
We present inelastic neutron scattering (INS) measurements of magnetic excitations in YbMnBi, which reveal features consistent with a direct coupling of magnetic excitations to…
