Possible two-component pairings in electron-doped BiSe based on a tight-binding model
Lei Hao, C. S. Ting
Recent experiments show the spontaneous breaking of rotational symmetry in the superconducting topological insulators MBiSe (M represents Cu, Sr, or Nd), suggesti…
Nematic superconductivity in CuBiSe: The surface Andreev bound states
Lei Hao, C. S. Ting
We study theoretically the topological surface states (TSSs) and the possible surface Andreev bound states (SABSs) of CuBiSe which is known to be a topological in…
Larkin-Ovchinnikov state of superconducting Weyl metals: Fundamental differences between pairings restricted and extended in the -space
Lei Hao, Rui Wang, Pavan Hosur +1
Two common approaches of studying theoretically the property of a superconductor are shown to have significant differences, when they are applied to the Larkin-Ovchinnikov state of…
Searching for two-dimensional Weyl superconductors in heterostructures
Lei Hao, C. S. Ting
Two-dimensional Weyl superconductor is the most elusive member of a group of materials with Weyl fermions as low-energy excitations. Here, we propose to realize this state in a het…
Topological Phase Transitions and a Two-Dimensional Weyl Superconductor in a Half-Metal/Superconductor Heterostructure
Lei Hao, C. S. Ting
We find a series of topological phase transitions in a half-metal/superconductor heterostructure, by tuning the direction of the magnetization of the half-metal film. These include…
Quantum anomalies in superconducting Weyl metals
Rui Wang, Lei Hao, Baigeng Wang +1
We theoretically study the quantum anomalies in the superconducting Weyl metals based on the topological field theory. It is demonstrated that the Fermi arc and the surface Andreev…
