Topological band structure of excitons in octochlore KTbF: an analog of the Luttinger Semimetal
Olivier Demortier, Françoise Damay, Paul McClarty +3
Understanding the symmetry and topology of band structures in crystalline solids has been among the defining themes of a generation of condensed matter physicists, with implication…
LT-scaling in depleted quantum spin ladders
Stanislaw Galeski, Kirill Yu. Povarov, Dominic Blosser +5
Using a combination of neutron scattering, calorimetry, Quantum Monte Carlo (QMC) simulations and analytic results we uncover confinement effects in depleted, partially magnetized…
Spin waves near the edge of halogen substitution induced magnetic order in Ni(ClBr)4SC(NH)
A. Mannig, K. Yu. Povarov, J. Ollivier +1
We report an inelastic neutron scattering study of magnetic excitations in a quantum paramagnet driven into a magnetically ordered state by chemical substitution, namely Ni(Cl$_{1-…
Doping-induced redistribution of magnetic spectral weight in substituted hexaborides CeLaB and CeNdB
S. E. Nikitin, P. Y. Portnichenko, A. V. Dukhnenko +6
We investigate the doping-induced changes in the electronic structure of CeB on a series of substituted CeB samples ( = La, Nd) using diffuse neutron scatteri…
Quantum criticality in a three dimensional spin system at zero field and pressure
K. Yu. Povarov, A. Mannig, G. Perren +4
We report spontaneous appearance of antiferromagnetic order in a model gapped quantum paramagnet Ni(ClBr)4SC(NH) induced by a change in bromine conce…
Emergent interacting spin islands in a depleted strong-leg Heisenberg ladder
D. Schmidiger, K. Yu. Povarov, S. Galeski +5
Properties of the depleted Heisenberg spin ladder material series (CHN)CuZnBr have been studied by the combination of magnetic measurements and neu…
