Edge states in a non-Hermitian topological crystalline insulator
Qiu-Yue Xu, Feng Liu, Chui-Zhen Chen +1
Breaking Hermiticity in topological systems gives rise to intriguing phenomena, such as the exceptional topology and the non-Hermitian skin effect. In this work, we study a non-Her…
Weyl nodes with higher-order topology in an optically driven nodal-line semimetal
Xiu-Li Du, Rui Chen, Rui Wang +1
Creating and manipulating topological states is a key goal of condensed matter physics. Periodic driving offers a powerful method to manipulate electronic states, and even to creat…
Pseudospin-Triplet Pairing in Iron-Chalcogenide Superconductors
Meng Zeng, Dong-Hui Xu, Zi-Ming Wang +2
We study superconductivity of electron systems with both spin and pseudospin-1/2 degrees of freedom. By solving linearized gap equations, we derive a weak coupling criterion for th…
Photoinduced Quantum Anomalous Hall States in the Topological Anderson Insulator
Zhen Ning, Baobing Zheng, Dong-Hui Xu +1
The realization of the quantum anomalous Hall (QAH) effect without magnetic doping attracts intensive interest since magnetically doped topological insulators usually possess inhom…
Higher-order topological Anderson insulators in quasicrystals
Tan Peng, Chun-Bo Hua, Rui Chen +3
The disorder effects on higher-order topological phases in periodic systems have attracted much attention. However, in aperiodic systems, such as quasicrystalline systems, the inte…
Disorder-induced chiral and helical Majorana edge modes in a two-dimensional Ammann-Beenker quasicrystal
Chun-Bo Hua, Zheng-Rong Liu, Tan Peng +3
Recent research on disorder effects in topological phases in quasicrystalline systems has received much attention. In this work, by numerically computing the (spin) Bott index and…
