Prominent Intrinsic Orbital Hall Effect in the 135 Kagome Metal Family and Orbital Responses in the Loop-Current Phase
Jianxin Huang, Rina Tazai, Youichi Yamakawa +1
The study of electronic orbital degrees of freedom, including the generation and control of orbital currents and orbital angular momentum, has emerged as a vibrant research field.…
Impact of multiband effects on non-Fermi-liquid transport phenomena in bilayer nickelates
Seiichiro Onari, Daisuke Inoue, Rina Tazai +2
Recently discovered high- superconductivity in thin-film bilayer nickelates LaNiO under ambient pressure has attracted great interest. Non-Fermi-liquid transport b…
Origin of switchable quasiparticle-interference chirality in loop-current phase of kagome metals measured by scanning-tunneling-microscopy
Seigo Nakazawa, Rina Tazai, Youichi Yamakawa +2
In the kagome superconductors AV3Sb5 (A=Cs,Rb,K), a cascade of correlated electron phases cause exotic symmetry-breaking quantum states. In particular, the dissipationless chiral l…
Paramagnon-Interference Mechanism for Three-Dimensional Bond Order in Kagome Metals AVSb (A=Cs, Rb, K): Analysis by the Density-Wave Equation
Seiichiro Onari, Rina Tazai, Youichi Yamakawa +1
The mechanism of CDW and its 3D structure are important fundamental issues in kagome metals. We have previously shown that, based on a 2D model, bond order (BO) emerges…
Giant critical current peak induced by pressure in kagome superconductor RbVSb
Lingfei Wang, Wenyan Wang, Tsz Fung Poon +11
Superconductivity can coexist or compete with other orders such as magnetism or density waves. Optimizing superconductivity requires identifying competing orders that may disrupt C…
Microscopic origin of period-four stripe charge-density-wave in kagome metal CsVSb
Yuma Murata, Rina Tazai, Youichi Yamakawa +2
The interplay between unconventional density waves and exotic superconductivity has attracted growing interest. Kagome superconductors ($A = \rm{K}, \rm{Rb}, \…
