A review on non-Hermitian skin effect
The past decades have witnessed the flourishing of non-Hermitian physics in non-conservative systems, leading to unprecedented phenomena of unidirectional invisibility, enhanced sensitivity and more
Real Non-Hermitian Energy Spectra Without Any Symmetry
Non-Hermitian models with real eigenenergies are highly desirable for their stability. Yet, most of the currently known ones are constrained by symmetries such as PT-symmetry, which is incompatible
Direction reversal of non-Hermitian skin effect via coherent coupling
Absolute negative mobility (ANM) in nonequilibrium systems depicts the possibility of particles propagating toward the opposite direction of an external force. We uncover in this work a phenomenon

Non-Hermitian Exceptional Landau Quantization in Electric Circuits.
This work identifies the low-energy physics with a generic real energy spectrum from the NH Landau quantization of exceptional points and rings, which can avoid the NH skin effect and provides a physical example of a quasiparticle moving in the complex plane.
Magnetic Suppression of Non-Hermitian Skin Effects.
A new aspect of this effect whereby, despite its topological origin, applying a magnetic field can largely suppress it, is discussed, which reveals a unique irrelevance of the generalized Brillouin zone in the standard non-Bloch band theory of non-Hermitian systems.
Non-Hermitian physics
A review is given on the foundations and applications of non-Hermitian classical and quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra, including Jordan normal
Non-Hermitian Skin Modes Induced by On-Site Dissipations and Chiral Tunneling Effect.
A no-go theorem for the emergence of skin modes is revealed and paves the way for searching for quantum systems with skin modes and studying their novel physical responses.
Interplay between Non-Hermitian Skin Effect and Magnetic Field: Skin Modes Suppression, Onsager Quantization and MT Phase Transition
The non-Hermitian skin effect (NHSE) refers to the exponential localization of the bulk wave functions to the system boundary, which corresponds to a directional current flow under the periodic
Vortex pinning and non-Hermitian quantum mechanics
A delocalization phenomenon is studied in a class of non-Hermitian random quantum-mechanical problems. Delocalization arises in response to a sufficiently large constant imaginary vector potential.
Topological Origin of Non-Hermitian Skin Effects.
It is revealed that the skin effect originates from intrinsic non-Hermitian topology, which explains the universal feature of the known skin effect, and leads to new types of the skin effects-symmetry-protected skin effects.
Topological Phases of Non-Hermitian Systems
Recent experimental advances in controlling dissipation have brought about unprecedented flexibility in engineering non-Hermitian Hamiltonians in open classical and quantum systems. A particular
Non-Hermitian Bulk-Boundary Correspondence and Auxiliary Generalized Brillouin Zone Theory.
It is shown that all the analytic properties of the GBZ can be characterized by an algebraic equation, the solution of which in the complex plane is dubbed as auxiliary GBZ (aGBZ), which provides an analytic approach to the spectral problem of open boundary non-Hermitian systems in the thermodynamic limit.
