Continuum of magnetic excitations in the Kitaev honeycomb iridate DLiIrO
Thomas Halloran, Yishu Wang, K. W. Plumb +12
Inelastic neutron scattering (INS) measurements of powder DLi)(Ir)O reveal low energy magnetic excitations with a scattering cross section that is broad in…
Magnetic ground state of the Kitaev NaCoTeO spin liquid candidate
Weiliang Yao, Yang Zhao, Yiming Qiu +4
As a candidate Kitaev material, NaCoTeO exhibits intriguing magnetism on a honeycomb lattice that is believed to be -symmetric. Here we report a neutron diffractio…
Quantum critical behavior in Ce(FeRu)Ge: the full story
Wouter Montfrooij, Tom Heitmann, Yiming Qiu +7
Systems with embedded magnetic ions that exhibit a competition between magnetic order and disorder down to absolute zero can display unusual low temperature behaviors of the resist…
Direct observation of the Higgs amplitude mode in a two-dimensional quantum antiferromagnet near the quantum critical point
Tao Hong, Masashige Matsumoto, Yiming Qiu +12
Spontaneous symmetry-breaking quantum phase transitions play an essential role in condensed matter physics. The collective excitations in the broken-symmetry phase near the quantum…
Unveiling the role of competing fluctuations at an unconventional quantum critical point
L. Poudel, J. M. Lawrence, L. S. Wu +7
Quantum critical points (QCPs) are widely accepted as a source of a diverse set of collective quantum phases of matter. A central question is how the order parameters of phases nea…
Polaron-mediated spin correlations in metallic and insulating LaMnO (=Ca, Sr, or Ba)
Joel S. Helton, Daniel M. Pajerowski, Yiming Qiu +6
Neutron spectroscopy measurements reveal short-range spin correlations near and above the ferromagnetic-paramagnetic phase transition in manganite materials of the form La$_{1-x}A_…
