Anti-higher-order topological insulators
Cheng-Ming Miao, Yu-Hao Wan, Ying-Tao Zhang +1
Duality is a fundamental concept in physics that connects complementary opposites like particles and holes. Similarly, while topological states in topological insulators localize a…
Second-order topological insulator induced by compensated altermagnetism without bulk spin splitting
Lizhou Liu, Qing-Feng Sun, Ying-Tao Zhang
We theoretically demonstrate a second-order topological insulating phase induced by compensated altermagnetism, while keeping the bulk gap unchanged, in a two-dimensional topologic…
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…
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…
