Engineering topologically protected zero-dimensional interface end states in antiferromagnetic heterojunction graphene nanoflakes
Cheng-Ming Miao, Yu-Hao Wan, Qing-Feng Sun +1
We investigate the energy band structure and energy levels of a heterojunction composed of two antiferromagnetic graphene nanoflakes with opposite in-plane antiferromagnetic orderi…

Second-order topological corner states in zigzag graphene nanoflake with different types of edge magnetic configurations
Cheng-Ming Miao, Qing-Feng Sun, Ying-Tao Zhang
We study the energy spectrum and energy levels of the extended Kane-Mele model with magnetic atoms on their zigzag edges. It is demonstrated that the edges of ferromagnetism or ant…

Topological phase transition driven by magnetic field in one-dimensional topological superconductor rings
Cheng-Ming Miao, Qing-Feng Sun, Ying-Tao Zhang
We study the energy spectrum and transport property of a one-dimensional Kitaev quantum ring in a threading magnetic field. It is demonstrated that the magnetic field can effective…
