Crystal electric field excitations and an effective-spin- ground doublet in the hyperkagome magnet YbScGaO
Tingjun Zhang, Zehao Wang, Douglas L. Abernathy +4
We use inelastic neutron scattering (INS) to determine the crystal electric field (CEF) excitations of Yb in the rare-earth hyperkagome magnet YbScGaO. Th…
Field-induced first order transitions and phase coexistence in the Kitaev quantum spin liquid candidate BaCo2(AsO4)2
Tanner J. Legvold, Bin Gao, Rong-Zhu Lin +9
BaCo2(AsO4)2 (BCAO) is an insulating Kitaev quantum spin liquid candidate with a rich low-temperature phase diagram. Below 5 K, it exhibits double-zigzag magnetic order. Upon appli…
Spectroscopic Demarcation of Emergent Photons and Spinons in a Dipolar-Octupolar Quantum Spin Liquid
Bin Gao, Zhengbang Zhou, Tingjun Zhang +4
The identification of fractionalized excitations in quantum spin liquids (QSLs) remains a central challenge in condensed matter physics. In dipolar-octupolar (DO) pyrochlores, such…
Signatures of bi-altermagnetism revealed by sublattice-specific circular dichroism in resonant inelastic X-ray scattering
G. Channagowdra, A. Singh, H. Y. Huang +9
An altermagnet is a recently identified class of magnets that exhibit a zero net magnetic moment but break symmetry under the combined operations of parity and time reversal. It ty…
Signatures of three-state Potts nematicity in spin excitations of the van der Waals antiferromagnet FePSe
Weiliang Yao, Viviane Peçanha Antonio, Devashibhai Adroja +6
In two-dimensional (2D) nearly square-lattice quantum materials, electron correlations can induce an electronic nematic phase with twofold rotational () symmetry that profound…
Absence of Acoustic Phonon Anomaly in a Kagome Metal with Short-ranged Structural Modulation
Weiliang Yao, Supeng Liu, Zifan Xu +9
Kagome lattice VSb ( = K, Rb, and Cs) superconductors without magnetism from vanadium -electrons are intriguing because they have a novel charge density wave (CDW)…
Spin Excitation Continuum in the Exactly Solvable Triangular-Lattice Spin Liquid CeMgAl11O19
Bin Gao, Tong Chen, Chunxiao Liu +17
In magnetically ordered insulators, elementary quasiparticles manifest as spin waves - collective motions of localized magnetic moments propagating through the lattice - observed v…
Emergent photons and fractionalized excitations in a quantum spin liquid
Bin Gao, Félix Desrochers, David W. Tam +6
A quantum spin liquid (QSL) arises from a highly entangled superposition of many degenerate classical ground states in a frustrated magnet, and is characterized by emergent gauge f…
