Moiré pattern of spin liquid and Neel magnet in a Kitaev chain
R. Wang, P. Wang, K. L. Zhang +1
A moiré pattern occurs when two periodic structures in a system have a slight mismatch period, resulting the coexistence of distinct phases in different large-scale spacial regions…
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…
Quantum transport in non-Hermitian impurity array
K. L. Zhang, X. M. Yang, Z. Song
We study the formation of band gap bound states induced by a non-Hermitian impurity embedded in a Hermitian system. We show that a pair of bound states emerges inside the band gap…
