Restoration of non-Hermitian bulk-boundary correspondence by counterbalancing skin effect
Yi-Xin Xiao, Zhao-Qing Zhang, C. T. Chan
The non-Hermitian skin effect (NHSE) undermines the conventional bulk-boundary correspondence (BBC) since it results in a distinct bulk spectrum in open-boundary systems compared t…
Edge and corner states in 2D non-Abelian topological insulators from an eigenvector frame rotation perspective
Tianshu Jiang, Ruo-Yang Zhang, Qinghua Guo +2
We propose the concept of 2D non-Abelian topological insulator which can explain the energy distributions of the edge states and corner states in systems with parity-time symmetry.…
Observation of boundary induced chiral anomaly bulk states and their transport properties
Mudi Wang, Qiyun Ma, Shan Liu +5
The robust transport of edge modes is perhaps the most useful property of topological materials. The existence of edge modes is guaranteed by the bulk-edge correspondence, which st…
Topology in non-Hermitian Chern insulators with skin effect
Yi-Xin Xiao, C. T. Chan
The non-Hermitian skin effect can arise in materials that have asymmetric hoppings between atoms or resonating units, which makes the bulk eigenspectrum sensitive to boundary condi…
Four-band non-Abelian topological insulator and its experimental realization
Tianshu Jiang, Qinghua Guo, Ruo-Yang Zhang +3
Very recently, increasing attention has been focused on non-Abelian topological charges, e.g. the quaternion group Q8. Different from Abelian topological band insulators, these sys…
Photonic nodal lines with quadrupole Berry curvature distribution
Dongyang Wang, Biao Yang, Ruo-Yang Zhang +4
In periodic systems, nodal lines are loops in the three-dimensional momentum space where two bands are degenerate with each other. Nodal lines exhibit rich topological features as…
Casimir induced instabilities at metallic surfaces and interfaces
Kun Ding, Daigo Oue, C. T. Chan +1
Surface plasmons subject to a surface distortion split asymmetrically in energy resulting in a net lowering of zero-point energy. This is because surface plasmon eigenvalues are th…
