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…

Field-direction sensitivity of Kondo hybridization in UTe $_{2}$

Thomas Halloran, Gicela Saucedo Salas, Sylvia K. Lewin +6

Neutron scattering experiments on the spin-triplet superconductor UTe $_{2}$ have established that the dominant low-energy magnetic response is along Brillouin zone boundaries, resemb…

Evidence for itinerant electron-local moment interaction in Li-doped $α$ -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 $α$ -MnTe. Introdu…

Quenched Disorder in the Triangular Lattice Antiferromagnet YbZn $_{2}$ GaO $_{5}$

Leshan Zhao, Tong Chen, Matthew B. Stone +4

We investigate the crystal electric field (CEF) excitations of Yb $^{3 +}$ ions in powder samples of the triangular-lattice rare-earth-based antiferromagnet YbZn $_{2}$ GaO $_{5}$ using ine…

Experimental Evidence for Non-spherical Magnetic Form Factor in Ru $^{3 +}$

Colin L. Sarkis, John W. Villanova, Casey Eichstaedt +9

The Mott insulator $α$ -RuCl $_{3}$ has generated great interest in the community due to its possible field-induced Kitaev quantum spin liquid state. Despite enormous effort spent tryi…
