Spectroscopic Signatures of Interlayer Coupling in Janus MoSSe/MoS2 Heterostructures
Kunyan Zhang, Yunfan Guo, Daniel T. Larson +5
The interlayer coupling in van der Waals heterostructures governs a variety of optical and electronic properties. The intrinsic dipole moment of Janus transition metal dichalcogeni…
A flat band-induced correlated kagome metal
Linda Ye, Shiang Fang, Min Gu Kang +11
The notion of an electronic flat band refers to a collectively degenerate set of quantum mechanical eigenstates in periodic solids. The vanishing kinetic energy of flat bands relat…
A magnetic Weyl semimetallic phase in thin films of EuIrO
Xiaoran Liu, Shiang Fang, Yixing Fu +17
The interplay between electronic interactions and strong spin-orbit coupling is expected to create a plethora of fascinating correlated topological states of quantum matter. Of par…
Twofold van Hove singularity and origin of charge order in topological kagome superconductor CsV3Sb5
Mingu Kang, Shiang Fang, Jeong-Kyu Kim +14
The layered vanadium antimonides AV3Sb5 (A = K, Rb, Cs) are a recently discovered family of topological kagome metals with a rich phenomenology of strongly correlated electronic ph…
Ferromagnetic helical nodal line and Kane-Mele spin-orbit coupling in kagome metal Fe3Sn2
Shiang Fang, Linda Ye, Madhav Prasad Ghimire +8
The two-dimensional kagome lattice hosts Dirac fermions at its Brillouin zone corners K and K', analogous to the honeycomb lattice. In the density functional theory electronic stru…
