Second-order topological insulator induced by compensated altermagnetism without bulk spin splitting
Lizhou Liu, Qing-Feng Sun, Ying-Tao Zhang
The paper theoretically shows that a two‑dimensional topological insulator film can host a second‑order topological insulating phase when a compensated altermagnetic term is added,…
Engineering Two-Dimensional Hybrid-Order Topological Insulators via Trilayer Coupling
Lizhou Liu, Cheng-Ming Miao, Qing-Feng Sun
The paper proposes an interlayer‑engineering scheme in a trilayer quantum anomalous Hall system to create a two‑dimensional hybrid‑order topological insulator that simultaneously h…
Engineering chiral-induced spin selectivity in an artificial topological quantum well
Lizhou Liu, Peng-Yi Liu, Tian-Yi Zhang +1
Chiral-induced spin selectivity (CISS) is a striking phenomenon in which spin-unpolarized electrons become spin-polarized after traversing a chiral medium. Theoretical studies have…
Tunable two-dimensional Dirac-Weyl semimetal phase induced by altermagnetism
Lizhou Liu, Qing-Feng Sun, Ying-Tao Zhang
We demonstrate a tunable Dirac-Weyl semimetal phase in two dimensions, realized by introducing in-plane d-wave altermagnetism into a Dirac system. This phase hosts both a central D…
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…
