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{…
Signature of edge states in resonant wave scattering
H. S. Xu, K. L. Zhang, L. Jin +1
Particle beam scattering is a conventional technique for detecting the nature of matter. We studied the scattering problem of a cluster connected to multiple leads. We established…
Symmetry-Protected Scattering in Non-Hermitian Linear Systems
L. Jin, Z. Song
Symmetry plays fundamental role in physics and the nature of symmetry changes in non-Hermitian physics. Here the symmetry-protected scattering in non-Hermitian linear systems is in…
Non-Hermitian Aharonov-Bohm Cage
S. M. Zhang, L. Jin
Aharonov-Bohm (AB) cage has a spectrum fully constituted by the flat bands and has the capacity to confine arbitrary excitation. The confined excitation in coupled waveguides propa…
Non-Hermitian phase transition and eigenstate localization induced by asymmetric coupling
P. Wang, L. Jin, Z. Song
We investigate a uniformly coupled non-Hermitian system with asymmetric coupling amplitude. The asymmetric coupling equals to a symmetric coupling threaded by an imaginary gauge fi…
