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…
Quantum Hall effect originated from helical edge states in CdAs
Rui Chen, C. M. Wang, Tianyu Liu +2
The recent experimental observations of the quantum Hall effect in 3D topological semimetals have attracted great attention, but there are still debates on its origin. We systemati…
Field-Tunable One-Sided Higher-Order Topological Hinge States in Dirac Semimetals
Rui Chen, Tianyu Liu, C. M. Wang +2
Recently, higher-order topological matter and 3D quantum Hall effects have attracted great attention. The Fermi-arc mechanism of the 3D quantum Hall effect proposed in Weyl semimet…
Phase transitions in intrinsic magnetic topological insulator with high-frequency pumping
Fang Qin, Rui Chen, Hai-Zhou Lu
In this work, we investigate the topological phase transitions in an effective model for a topological thin film with high-frequency pumping. In particular, our results show that t…
Realization of quasicrystalline quadrupole topological insulators in electrical circuits
Bo Lv, Rui Chen, Rujiang Li +9
Quadrupole topological insulators are a new class of topological insulators with quantized quadrupole moments, which support protected gapless corner states. The experimental demon…
