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, $S^{†} (H_{c}^{†}) S (H_{c}) = I$ , which is valid for any non-Hermitian s…

Tunable Aharonov-Bohm cages through anti- $P T$ -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…
