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…
