Spin density wave and van Hove singularity in the kagome metal CeTi3Bi4
Pyeongjae Park, Brenden R. Ortiz, Milo Sprague +15
Kagome metals with van Hove singularities near the Fermi level can host intriguing quantum phenomena such as chiral loop currents, electronic nematicity, and unconventional superco…
Simultaneous development of antiferromagnetism and local symmetry breaking in a kagome magnet (CoFe)Sn
Tsung-Han Yang, Shang Gao, Yuanpeng Zhang +6
CoSn and FeSn, two kagome-lattice metals, have recently attracted significant attention as hosts of electronic flat bands and emergent physical properties. However, current underst…
Quantum and classical spin dynamics across temperature scales in the S = 1/2 Heisenberg antiferromagnet
Pyeongjae Park, G. Sala, Daniel M. Pajerowski +6
Using the framework of semi-classical Landau-Lifshitz dynamics (LLD), we conduct a systematic investigation of the temperature-dependent spin dynamics in the S = 1/2 Heisenberg squ…
Anomalous continuum scattering and higher-order van Hove singularity in the strongly anisotropic S = 1/2 triangular lattice antiferromagnet
Pyeongjae Park, E. A. Ghioldi, Andrew F. May +10
The S = 1/2 triangular lattice antiferromagnet (TLAF) is a paradigmatic example of frustrated quantum magnetism. An ongoing challenge involves understanding the influence of exchan…
