Tunable Dual-Type Weyl Points in Dirac-Weyl Semimetal CaAgBi
Shenghao Huang, Heng Gao, Hongfei Wang +1
Dirac-Weyl semimetals host both Dirac and Weyl fermions and the exploration of material candidates with tunable topological properties is essential to realize topological spintroni…
Probing the Chirality of Trigonal Selenium and Tellurium by Spin and Orbital Hall Effects
Yuting Xiong, Yingjie Hu, Wei Ren +1
Chiral crystals exhibit enantiomer-dependent transport phenomena that generate pure spin or orbital currents, while the handedness sensitivity of spin and orbital Hall conductiviti…
Polarization Engineering of the Orbital Hall Conductivity in Two-dimensional Ferroelectric Higher-Order Topological Insulator TlS and SnS
