Fermion doubling theorems in 2D non-Hermitian systems for Fermi points and exceptional points
Zhesen Yang, A. P. Schnyder, Jiangping Hu +1
The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. H…
Symmetry-enforced band crossings in trigonal materials: Accordion states and Weyl nodal lines
Y. -H. Chan, Berkay Kilic, Moritz M. Hirschmann +4
Nonsymmoprhic symmetries, such as screw rotations or glide reflections, can enforce band crossings within high-symmetry lines or planes of the Brillouin zone. When these band degen…
Vortex Majorana braiding in a finite time
Thore Posske, Ching-Kai Chiu, Michael Thorwart
Abrikosov vortices in Fe-based superconductors are a promising platform for hosting Majorana zero modes. Their adiabatic exchange is a key ingredient for Majorana-based quantum com…
Jones polynomial and knot transitions in topological semimetals
Zhesen Yang, Ching-Kai Chiu, Chen Fang +1
Topological nodal line semimetals host stable chained, linked, or knotted line degeneracies in momentum space protected by symmetries. In this paper, we use the Jones polynomial as…
Scalable Majorana vortex modes in iron-based superconductors
Ching-Kai Chiu, T. Machida, Yingyi Huang +2
A vortex in an s-wave superconductor with a surface Dirac cone can trap a Majorana bound state with zero energy leading to a zero-bias peak (ZBP) of tunneling conductance. The iron…
Protocol for reading out Majorana vortex qubit and testing non-Abelian statistics
Chun-Xiao Liu, Dong E. Liu, Fu-Chun Zhang +1
The successful test of non-Abelian statistics not only serves as a milestone in fundamental physics but also provides a quantum gate operation in topological quantum computation. A…
