Tunable topological edge states in black phosphorus-like Bi(110)
Chen Liu, Shengdan Tao, Guanyong Wang +12
We have investigated the structures and electronic properties of ultra-thin Bi(110) films grown on an s-wave superconductor substrate using low-temperature scanning tunneling micro…

Band-Structure-Independent Topology from Nonsymmorphic Wannier Complexes
Qinghua He, Jie Zhang, Shengdan Tao +4
Nonsymmorphic symmetries can enforce band connectivity that obstructs a single-band Wannier description. We show that a fractional translation connecting distinct hig…
