Fidelity in topological superconductors with end Majorana fermions
Zhi Wang, Qi-Feng Liang, Dao-Xin Yao
Fidelity and fidelity susceptibility are introduced to investigate the topological superconductors with end Majorana fermions. A general formalism is established to calculate the f…
Proposal for Manipulation of Majorana Fermions in Nano-Patterned Semiconductor-Superconductor Heterostructure
Long-Hua Wu, Qi-Feng Liang, Zhi Wang +1
We investigate a heterostructure system with a spin-orbit coupled semiconductor sandwiched by an s-wave superconductor and a ferromagnetic insulator, which supports Majorana fermio…
Topological Single Electron Pumping Assisted by Majorana Fermions
Qi-Feng Liang, Zhi Wang, Xiao Hu
Single electron pumping based on the topological property of Majorana fermions (MFs) is proposed. The setup consists of a quantum dot and four nano topological superconductors (TSs…
Electrically Tunable Topological State in [111] Perovskite Materials with Antiferromagnetic Exchange Field
Qi-Feng Liang, Long-Hua Wu, Xiao Hu
A topological state with simultaneous nonzero Chern number and spin Chern number is possible for electrons on honeycomb lattice based on band engineering by staggered electric pote…
