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{…

Experimental demonstration of separating the waveparticle duality of a single photon with the quantum Cheshire cat
JiaKun Li, Kai Sun, Yan Wang +8
As a fundamental characteristic of physical entities, waveparticle duality describes whether a microscopic entity exhibits wave or particle attributes depending on the specific exp…
