Robust incoherent perfect absorption
H. S. Xu, L. Jin
A coherent perfect absorber is capable of completely absorbing input waves. However, the coherent perfect absorption severely depends on the superposition of the input waves, and t…
Edge State, Band Topology, and Time Boundary Effect in the Fine-Grained Categorization of Chern Insulators
H. C. Wu, H. S. Xu, L. C. Xie +1
We predict novel topological phases with broken time-reversal symmetry supporting the coexistence of opposite chiral edge states, which are fundamentally different from the photoni…
Pseudo-Hermiticity protects the energy-difference conservation in the scattering
H. S. Xu, L. Jin
Symmetry plays a fundamentally important role in physics. In this work, we find a conservation law, , which is valid for any non-Hermitian s…
Tunable Aharonov-Bohm cages through anti--symmetric imaginary couplings
S. M. Zhang, H. S. Xu, L. Jin
The Aharonov-Bohm (AB) cage enables localized confinement with nondiffractive propagation for arbitrary excitation. In this study, we introduce an anti-parity-time (anti-$\mathcal{…
High-order spectral singularity
H. S. Xu, L. C. Xie, L. Jin
Exceptional point and spectral singularity are two types of singularity that are unique to non-Hermitian systems. Here, we report the high-order spectral singularity as a high-orde…
Coherent resonant transmission
H. S. Xu, L. Jin
The reflectionless coherent light transport in the coupled resonator array is investigated in the presence of intra-resonator intermodal coupling between the clockwise and counterc…
