Protected valley states and generation of valley- and spin-polarized current in monolayer MA2Z4
Jiaren Yuan, Qingyuan Wei, Minglei Sun +4
The optical selection rules obeyed by two-dimensional materials with spin-valley coupling enable the selective excitation of carriers. We show that six members of the monolayer MA2…
Dirac Nodal Lines and Nodal Loops in a Topological Kagome Superconductor CsVSb
Zhanyang Hao, Yongqing Cai, Yixuan Liu +21
The intertwining of charge order, superconductivity and band topology has promoted the AVSb (A=K, Rb, Cs) family of materials to the center of attention in condensed matter…
Doping evolution of superconductivity, charge order and band topology in hole-doped topological kagome superconductors Cs(VTi)Sb
