The synergy between non-Hermitian concepts and topological ideas have led to very fruitful
activity in the recent years. Their interplay has resulted in a wide variety of new non …

The topological edge state distributes along the edge of a topological insulator which has
advantages in prohibiting radiation and reflection in the evolution dynamics because of the …

Symmetry-protected spectral topology in extended non-Hermitian quantum systems has
interesting manifestations such as dynamically anomalous chiral currents and skin effect. In …

We study a cluster Ising model with non-Hermitian external field which can be exactly solved
in the language of free fermions. By investigating the second derivative of energy density …

We show that one-dimensional Floquet trimer arrays with periodically oscillating
waveguides support two different and co-existing types of topological Floquet edge states in …

The multipartite non-Hermitian Su-Schrieffer-Heeger model is explored as a prototypical
example of one-dimensional systems with several sublattice sites for unveiling intriguing …

Topological phases of matter, originally derived from condensed matter physics, have been
extensively exploited in photonics and phononics, and recently in mechanical metamaterial …

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 qubit …

The dynamical and topological properties of non-Hermitian systems have attracted great
attention in recent years. In this work, we establish an intrinsic connection between two …

An attempt is made to study the quantum criticality in non-Hermitian system with topological
characterization. We use the zero mode solutions to characterize the topological phases …
