Phonon promoted charge density wave in topological kagome metal ScVSn
Yong Hu, Junzhang Ma, Yinxiang Li +21
Charge density wave (CDW) orders in vanadium-based kagome metals have recently received tremendous attention due to their unique properties and intricate interplay with exotic corr…
Anomalous quasiparticles in the zone center electron pocket of the kagomé ferromagnet Fe3Sn2
Sandy Adhitia Ekahana, Y. Soh, Anna Tamai +14
One material containing kagome bilayers and featuring both exceptional magnetism and electron transport is the ferromagnetic metal Fe3Sn2. Notwithstanding the widespread interest i…
Multiple mobile excitons manifested as sidebands in quasi-one-dimensional metallic TaSe3
Junzhang Ma, Simin Nie, Xin Gui +22
Charge neutrality and their expected itinerant nature makes excitons potential transmitters of information. However, exciton mobility remains inaccessible to traditional optical ex…
Topological Magnetic Phase in the Candidate Weyl Semimetal CeAlGe
P. Puphal, V. Pomjakushin, N. Kanazawa +9
We report the discovery of topological magnetism in the candidate magnetic Weyl semimetal CeAlGe. Using neutron scattering we find this system to host several incommensurate, squar…
Metal-to-insulator transition in Pt-doped TiSe driven by emergent network of narrow transport channels
Kyungmin Lee, Jesse Choe, Davide Iaia +13
Metal-to-insulator transitions (MIT) can be driven by a number of different mechanisms, each resulting in a different type of insulator -- Change in chemical potential can induce a…
Moderate hybridization effects revealed by ARPES in heavy-fermion Ce2IrIn8
H. -J. Liu, Y. -J. Xu, Y. -G. Zhong +9
We utilized high-resolution resonant angle-resolved photoemission spectroscopy (ARPES) to study the band structure and hybridization effect of the heavy-fermion compound Ce2IrIn8.…
NaFeCuAs: A pnictide insulating phase induced by on-site Coulomb interaction
C. E. Matt, N. Xu, B. Q. Lv +13
In the studies of iron-pnictides, a key question is whether their bad-metal state from which the superconductivity emerges lies in close proximity with a magnetically ordered insul…
Surface vs bulk electronic structures of a moderately correlated topological insulator YbB6 revealed by ARPES
N. Xu, C. E. Matt, E. Pomjakushina +14
Systematic angle-resolved photoemission spectroscopy (ARPES) experiments have been carried out to investigate the bulk and (100) surface electronic structures of a topological mixe…
