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…
Two-dimensional higher-order Weyl semimetals
Lizhou Liu, Qing-Feng Sun, Ying-Tao Zhang
We propose a theoretical scheme to realize two-dimensional higher-order Weyl semimetals using a trilayer topological insulator film coupled with a d-wave altermagnet. Our results s…
