Anomalous hybridization of spectral winding topology in quantized steady-state responses
Hui-Qiang Liang, Sen Mu, Jiangbin Gong +1
Quantized response is one distinguishing feature of a topological system. In non-Hermitian systems, the spectral winding topology yields quantized steady-state response. By conside…
Arbitrary entangled state transfer via a topological qubit chain
Chong Wang, Linhu Li, Jiangbin Gong +1
Quantum state transfer is one of the basic tasks in quantum information processing. We here propose a theoretical approach to realize arbitrary entangled state transfer through a q…
Non-Hermitian pseudo mobility edge in a coupled chain system
Sen Mu, Longwen Zhou, Linhu Li +1
In this work, we explore interesting consequences arising from the coupling between a clean non-Hermitian chain with skin localization and a delocalized chain of the same length un…
Topological properties of non-Hermitian Creutz Ladders
Hui-Qiang Liang, Linhu Li
In this work we study topological properties of the one-dimensional Creutz ladder model with different non-Hermitian asymmetric hoppings and on-site imaginary potentials, and obtai…
Exact solution of single impurity problem in non-reciprocal lattices: impurity induced size-dependent non-Hermitian skin effect
Yanxia Liu, Yumeng Zeng, Linhu Li +1
Non-Hermitian non-reciprocal systems are known to be extremely sensitive to boundary conditions, exhibiting diverse localizing behaviors and spectrum structures when translational…
Non-Hermitian Pseudo-Gaps
Linhu Li, Ching Hua Lee
The notion of a band gap is ubiquitous in the characterization of matter. Particularly interesting are pseudo-gaps, which are enigmatic regions of very low density of states that h…
Delocalization of topological edge states
Weiwei Zhu, Wei Xin Teo, Linhu Li +1
The non-Hermitian skin effect (NHSE) in non-Hermitian lattice systems depicts the exponential localization of eigenstates at system's boundaries. It has led to a number of counter-…
