Photonic crystalThe hybrid skin-topological effect has attracted widespread attention. This phenomenon arises from the interplay between the non-Hermitian skin effect (NHSE) and topological effects, hence it is
The concept of non-Hermiticity has expanded the understanding of band topology, leading to the emergence of counter-intuitive phenomena. An example is the non-Hermitian skin effect (NHSE)1–7, which involves the concentration of eigenstates at the bounda
We uncover here a class of criticality, dubbed the “critical non-Hermitian skin effect (CNHSE)”, where the eigenenergies and eigenstates in the thermodynamic limit “jump” between different skin solutions discontinuously across the critical point. This is distinct from previously known phase trans...
发生NHSE前厄米边界态的数目会比体态降一维，而形成skin state这一步不降维，所以skin state是O(Ld−...

The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates the introduction of non-Hermitian band topology. So far, all NHSE observations are based on one type of non-Hermitian ba...
We demonstrate that a correlated equilibrium f-electron system with time-reversal symmetry can exhibit a Z2 non-Hermitian skin effect of quasiparticles. In particular, we analyze a two-dimensional periodic Anderson model with spin-orbit coupling by combining the dynamical mean-field theory (DMFT) an...
The Wannier-Stark localization dynamically alters the entanglement behavior of non-Hermitian free fermions. Utilizing the single-particle correlation matrix technique, we analyze the effective Hamiltonian of these fermions with a Wannier-Stark ladder. Under open boundary conditions, we observe the steady ...
Non-Hermitian photonics and topological photonics, as new research fields in optics, have attracted much attention in recent years, accompanying by a great deal of new physical concepts and novel effects emerging. The two fields are gradually crossed dur
