Coherent confinement and unidirectional dynamics of a wave packet induced by a non-Hermitian Su-Schrieffer-Heeger segment
K. L. Zhang, Z. Song
The competition between staggered imaginary potentials and lattice dimerization results in a unidirectional propagating coalescing state of a non-Hermitian Su-Schrieffer-Heeger (SS…

Semi-localization transition driven by a single asymmetrical tunneling
P. Wang, K. L. Zhang, Z. Song
A local impurity usually only strongly affects few single-particle energy levels, thus cannot induce a quantum phase transition (QPT), or any macroscopic quantum phenomena in a man…

Exceptional point induced lasing dynamics in a non-Hermitian system
K. L. Zhang, P. Wang, Z. Song
Non-Hermitian systems exhibit many peculiar dynamic behaviors which never showed up in Hermitian systems. The existence of spectral singularity (SS) for a non-Hermitian scattering…
