Orbital-selective oxygen holes in cuprate ladders beyond the Zhang-Rice paradigm
Chengyun Hua, Tianran Chen, Isaac C. Ownby +13
The electronic structure of the spin-ladder cuprate Sr14Cu24O41 challenges the presumed universality of the Zhang-Rice singlet (ZRS) framework and models based exclusively on Cu-O…
Winding feature and thermal evolution of the Dirac magnons in CrI
Weiliang Yao, Matthew B. Stone, Colin L. Sarkis +4
Two-dimensional honeycomb lattice ferromagnet chromium tri-iodide (CrI) has attracted tremendous interest because it retains ferromagnetism down to the monolayer limit and host…
Benchmarking quantum simulation with neutron-scattering experiments
Yi-Ting Lee, Keerthi Kumaran, Bibek Pokharel +7
Realistic simulation of quantum materials is a central goal of quantum computation. Although quantum processors have advanced rapidly in scale and fidelity, it has remained unclear…
Field-direction sensitivity of Kondo hybridization in UTe
Thomas Halloran, Gicela Saucedo Salas, Sylvia K. Lewin +6
Neutron scattering experiments on the spin-triplet superconductor UTe have established that the dominant low-energy magnetic response is along Brillouin zone boundaries, resemb…
Intermediate Field Spin(on) Dynamics in -RuCl
C. L. Sarkis, K. D. Dixit, P. Rao +11
We present comprehensive inelastic neutron spectroscopic maps of the magnetic field-induced disordered phase of the Kitaev quantum spin liquid candidate material -RuCl. For…
Evidence for itinerant electron-local moment interaction in Li-doped -MnTe
Tingjun Zhang, Steven J. Gomez Alvarado, Sijie Xu +17
We use inelastic neutron scattering (INS) and angle-resolved photoemission spectroscopy (ARPES) to study the impact of Li doping on the semiconducting altermagnet -MnTe. Introdu…
Quenched Disorder in the Triangular Lattice Antiferromagnet YbZnGaO
Leshan Zhao, Tong Chen, Matthew B. Stone +4
We investigate the crystal electric field (CEF) excitations of Yb ions in powder samples of the triangular-lattice rare-earth-based antiferromagnet YbZnGaO using ine…
Review of honeycomb-based Kitaev materials with zigzag magnetic ordering
V. Ovidiu Garlea, Colin L. Sarkis
The search for a Kitaev quantum spin liquid in crystalline magnetic materials has fueled intense interest in the two-dimensional honeycomb systems. Many promising candidate Kitaev…
Experimental Evidence for Non-spherical Magnetic Form Factor in Ru
Colin L. Sarkis, John W. Villanova, Casey Eichstaedt +9
The Mott insulator -RuCl has generated great interest in the community due to its possible field-induced Kitaev quantum spin liquid state. Despite enormous effort spent tryi…
Structure transition and zigzag magnetic order in Ir/Rh-substituted honeycomb lattice RuCl3
Zachary Morgan, Iris Ye, Colin L. Sarkis +3
We report magnetization and neutron diffraction studies on crystal and magnetic structures of Ir- and Rh-substituted honeycomb lattice -RuCl. The iridium or rhodium atoms ar…
