Structural Disorder Induced Second-order Topological Insulators in Three Dimensions
Jiong-Hao Wang, Yan-Bin Yang, Ning Dai +1
Higher-order topological insulators are established as topological crystalline insulators protected by crystalline symmetries. One celebrated example is the second-order topologica…
Higher-order Topological Anderson Insulators
Yan-Bin Yang, Kai Li, L. -M. Duan +1
We study disorder effects in a two-dimensional system with chiral symmetry and find that disorder can induce a quadrupole topological insulating phase (a higher-order topological p…
Hinge solitons in three-dimensional second-order topological insulators
Yu-Liang Tao, Ning Dai, Yan-Bin Yang +2
A second-order topological insulator in three dimensions refers to a topological insulator with gapless states localized on the hinges, which is a generalization of a traditional t…
Observation of Dynamical Quantum Phase Transition with Correspondence in Excited State Phase Diagram
T. Tian, H. -X. Yang, L. -Y. Qiu +4
Dynamical quantum phase transitions are closely related to equilibrium quantum phase transitions for ground states. Here, we report an experimental observation of a dynamical quant…
