From weakly interacting spinons to tightly bound triplons in the frustrated quantum spin-Peierls chain
Pyeongjae Park, Bo Xiao, Karolina Górnicka +7
Fractionalized quasiparticles and their confinement into emergent bound states lie at the heart of modern quantum magnetism. While the evolution into magnonic bound states has been…
Crystal field splittings and magnetic ground state of the square-lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 with Jeff = 1/2
Pyeongjae Park, Qianli Ma, G. Sala +5
We report on the crystal field level splitting and magnetic ground state of the Jeff = 1/2 square lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 using powder inelastic neutron sca…
Dipolar and quadrupolar correlations in the Re-based double perovskites BaYReO and BaScReO
Otkur Omar, Yang Zhang, Qiang Zhang +8
Double perovskites containing heavy transition metal ions are an important family of compounds for the study of the interplay between electron correlation and spin-orbit coupling.…
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…
