Two quantum spin liquid states coexisting in the kagome antiferromagnet herbertsmithite
Arthur C. Campello, Shengtao Jiang, Wei He +5
Herbertsmithite (ZnCu(OH)Cl) is one of the most extensively studied quantum spin liquid (QSL) candidates, yet the precise nature of its ground state remains unresolved.…
Quantifying the Phase Diagram and Hamiltonian of Kagome Antiferromagnets: Bridging Theory and Experiment
Shengtao Jiang, Arthur C. Campello, Wei He +4
Spin- kagome antiferromagnets are leading candidates for realizing quantum spin liquid (QSL) ground states. While QSL ground states are predicted for the pure Heisenberg model…
Local probe investigation of the spin dynamics in the kagome and inter-layers of orthorhombic barlowite Cu(OD)FBr: Br and Cu NQR study
Takashi Imai, Jiaming Wang, Rebecca W. Smaha +3
We report Br and Cu nuclear quadrupole resonance (NQR) in the paramagnetic state above K of the antiferromagnetic orthorhombic phase of barlowite Cu…
Emergence of spin singlets with inhomogeneous gaps in the kagome Heisenberg antiferromagnets Zn-barlowite and herbertsmithite
Jiaming Wang, Weishi Yuan, Philip M. Singer +5
The kagome Heisenberg antiferromagnet formed by frustrated spins arranged in a lattice of corner-sharing triangles is a prime candidate for hosting a quantum spin liquid (QSL) grou…
Freezing of the Lattice in the Kagome Lattice Heisenberg Antiferromagnet Zn-barlowite ZnCu(OD)FBr
Jiaming Wang, Weishi Yuan, Philip M. Singer +5
We use Br nuclear quadrupole resonance (NQR) to demonstrate that ultra slow lattice dynamics set in below the temperature scale set by the Cu-Cu super-exchange interaction $…
Tilted stripes origin in revealed by anisotropic next-nearest neighbor hopping
Wei He, Jiajia Wen, Hong-Chen Jiang +6
Spin- and charge- stripe order has been extensively studied in the superconducting cuprates, among which underdoped (LSCO)…
Site-Specific Structure at Multiple Length Scales in Kagome Quantum Spin Liquid Candidates
Rebecca W. Smaha, Idris Boukahil, Charles J. Titus +11
Realizing a quantum spin liquid (QSL) ground state in a real material is a leading issue in condensed matter physics research. In this pursuit, it is crucial to fully characterize…
Materializing Rival Ground States in the Barlowite Family of Kagome Magnets: Quantum Spin Liquid, Spin Ordered, and Valence Bond Crystal States
Rebecca W. Smaha, Wei He, Jack Mingde Jiang +13
The spin- kagome antiferromagnet is considered an ideal host for a quantum spin liquid ground state. We find that when the bonds of the kagome lattice are modulated wi…
Synthesis-Dependent Properties of Barlowite and Zn-Substituted Barlowite
Rebecca W. Smaha, Wei He, John P. Sheckelton +2
The mineral barlowite, Cu(OH)FBr, has been the focus of recent attention due to the possibility of substituting the interlayer Cu site with non-magnetic ions to deve…
High pressure x-ray study of spin-Peierls physics in the quantum spin chain material TiOCl
Costel R. Rotundu, Jiajia Wen, Wei He +3
The application of pressure can induce transitions between unconventional quantum phases in correlated materials. The inorganic compound TiOCl, composed of chains of S=1/2 Ti ions,…
