Helical Fermi Arc in Altermagnetic Weyl Semimetal
Yu-Hao Wan, Cheng-Ming Miao, Peng-Yi Liu +1
We investigate the topological properties of modified Dirac Hamiltonians with an altermagnetic mass term and reveal a novel mechanism for realizing altermagnetic Weyl semimetals. U…
Characterizing second-order topological insulators via entanglement topological invariant in two-dimensional systems
Yu-Long Zhang, Cheng-Ming Miao, Qing-Feng Sun +2
Higher-order topological insulators have attracted significant interest in recent years. However, identifying a universal topological invariant capable of characterizing higher-ord…
Tunable Majorana corner states driven by superconducting phase bias in a vertical Josephson junction
Cheng-Ming Miao, Yu-Hao Wan, Ying-Tao Zhang +1
The realization and manipulation of Majorana zero modes is a key step in achieving topological quantum computation. In this paper, we demonstrate the existence of Majorana corner s…
Two-Dimensional Higher-Order Topological Metals
Lizhou Liu, Cheng-Ming Miao, Qing-Feng Sun +1
We investigate the energy band structure and energy levels of graphene with staggered intrinsic spin-orbit coupling and in-plane Zeeman fields. Our study demonstrates that staggere…
Two-dimensional Dirac semimetals with tunable edge states
Lizhou Liu, Cheng-Ming Miao, Qing-Feng Sun +1
We theoretically propose a design for two-dimensional Dirac semimetals using a bilayer-modified Bernevig-Hughes-Zhang (BHZ) model. By introducing new sites into the BHZ model, we e…
Quantum spin Hall effect in bilayer honeycomb lattices with C-type antiferromagnetic order
Lizhou Liu, Cheng-Ming Miao, Qing-Feng Sun +1
We propose a scheme to realize time-reversal symmetry-broken quantum spin Hall insulators using bilayer honeycomb lattices, combining intrinsic spin-orbit coupling, C-type antiferr…
