Intriguing kagome topological materials
Qi Wang, Hechang Lei, Yanpeng Qi +1
Topological quantum materials with kagome lattice have become the emerging frontier in the context of condensedmatter physics. Kagome lattice harbors strongmagnetic frustration and…
Ultrahigh Anomalous Nernst Thermopower and Thermal Hall Angle in YbMnBi2
Jiamin Wen, Kaustuv Manna, Dung Vu +5
Thermoelectrics (TEs) are solid-state devices that can realize heat-electricity conversion. Transverse TEs require materials with a large Nernst effect, which typically requires a…
FeGe as a building block for the kagome 1:1, 1:6:6, and 1:3:5 families: hidden d-orbital decoupling of flat band sectors, effective models and interaction Hamiltonians
Yi Jiang, Haoyu Hu, Dumitru CÄlugÄru +5
The electronic structure and interactions of kagome materials, such as the 1:1 (FeGe) and 1:6:6 (MgFe6Ge6) classes, are complicated and involve many orbitals and bands around the F…
Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
In-situ monitoring the magnetotransport signature of topological transitions in the chiral magnet MnPtSn
Andy Thomas, Darius Pohl, Alexander Tahn +8
Emerging magnetic fields related to the presence of topologically protected spin textures such as skyrmions are expected to give rise to additional, topology-related contributions…
