Topological triple phase transition in non-Hermitian Floquet quasicrystals

Sebastian Weidemann et al.

Summary: Phase transitions in non-Hermitian quasicrystals can be mutually interlinked, and the intertwinement of symmetry breaking, topology, and mobility phase transitions is observed in this study using photonic quantum walks.

Non-Hermitian Edge Burst

Wen-Tan Xue et al.

Summary: We have discovered an unexpected non-Hermitian phenomenon called "edge burst" in non-Hermitian quantum dynamics. This phenomenon occurs in a class of non-Hermitian quantum walk in periodic lattices with open boundary conditions, where a large portion of loss happens at the system boundary. The edge burst is caused by the interplay between two unique non-Hermitian phenomena: non-Hermitian skin effect and imaginary gap closing. We have also established a universal bulk-edge scaling relation that explains the non-Hermitian edge burst, which can be experimentally observed in various non-Hermitian systems including quantum-optical and cold-atom platforms.

Connections between the open-boundary spectrum and the generalized Brillouin zone in non-Hermitian systems

Deguang Wu et al.

Summary: This paper investigates the connections between the periodic-boundary spectrum, open-boundary spectrum, and the generalized Brillouin zone in a one-dimensional non-Hermitian system. It proposes an efficient numerical method for accurately calculating these properties. Furthermore, the study extends these connections to non-Hermitian systems in the symplectic symmetry class.

Topological complex-energy braiding of non-Hermitian bands

Kai Wang et al.

Summary: The recent theoretical work discovered that the braid group characterizes the topology of non-Hermitian periodic systems, where the complex band energies can braid in momentum space. This study introduces a tight-binding lattice model that can achieve arbitrary elements in the braid group of two strands B-2 and experimentally demonstrates topological complex-energy braiding of non-Hermitian bands in a synthetic dimension. The results provide a direct demonstration of the braid-group characterization of non-Hermitian topology and open a pathway for designing and realizing topologically robust phases in open classical and quantum systems.

Detecting Non-Bloch Topological Invariants in Quantum Dynamics

Kunkun Wang et al.

Summary: Non-Bloch topological invariants have been dynamically detected in single-photon quantum walks, revealing their robustness against symmetry-preserving disorders and consistency with theoretical predictions. The experiments performed far from boundaries highlight these invariants as intrinsic properties of the system persisting in the thermodynamic limit, shedding new light on experimental investigation of non-Hermitian topology.

Exceptional topology of non-Hermitian systems

Emil J. Bergholtz et al.

Summary: This review discusses the current understanding of the role of topology in non-Hermitian systems and its physical consequences in dissipative settings, focusing on the concept of exceptional degeneracies and its distinct phenomena, as well as the new notions of gapped phases in single-band systems. The unique sensitivity of non-Hermitian matrices to boundary conditions is highlighted, leading to anomalous relationships between bulk and boundary physics. Additionally, applications of non-Hermitian topology in classical and quantum systems are reviewed, showing its relevance beyond the field of topological phases.

Non-Hermitian Skin Effects in Hermitian Correlated or Disordered Systems: Quantities Sensitive or Insensitive to Boundary Effects and Pseudo-Quantum-Number

Nobuyuki Okuma et al.

Summary: In the condensed matter community, there is a common belief that bulk quantities become insensitive to boundary conditions in the infinite-volume limit. However, recent research has shown that for non-Hermitian Hamiltonians, spectra strongly depend on boundary conditions, which can have significant effects in Hermitian correlated or disordered systems. Additionally, non-normal pseudospectra can be tested through sharp optical absorption, indicating the emergence of pseudo quantum numbers as a result of high non-normality.

Summary: This study demonstrates a versatile approach to generate and control the non-Hermitian skin effect for photons using synthetic gauge fields. By utilizing indirectly coupled optical ring resonator arrays with long-range couplings and on-site gain and loss, the researchers have validated the appearance of the skin effect under certain conditions and explored its properties and potential applications in propagation effects.

Exact Solution of Non-Hermitian Systems with Generalized Boundary Conditions: Size-Dependent Boundary Effect and Fragility of the Skin Effect

Cui-Xian Guo et al.

Summary: The study reveals the sensitivity of systems with non-Hermitian skin effects to boundary conditions and lattice size. In one-dimensional non-Hermitian models, the existence of non-Hermitian skin effects is identified even when one of the boundary hopping terms vanishes. However, it is shown that in the thermodynamic limit, this skin effect is fragile to any tiny boundary perturbations.

Non-Hermitian skin effect beyond the tight-binding models

Stefano Longhi

Summary: The energy bands of non-Hermitian systems have nontrivial topological features that result from the complex nature of the energy spectrum, characterized by integer nonzero winding numbers. The nontrivial winding provides the topological signature of the non-Hermitian skin effect (NHSE) at lattice edges under open boundary conditions. While most current results rely on tight-binding models of non-Hermitian systems, exact Bloch wave function analysis of the NHSE and related topological band theory is still lacking.

Non-Hermitian band topology with generalized inversion symmetry

Ryo Okugawa et al.

Summary: By generalizing inversion symmetry, this study provides a method to detect skin effects and exceptional points in non-Hermitian systems. The parity of winding numbers can be determined from energy eigenvalues on inversion-invariant momenta in the presence of generalized inversion symmetry. The simple expressions for winding numbers facilitate the analysis of skin effects and exceptional points in non-Hermitian bands.

Quantum anomaly, non-Hermitian skin effects, and entanglement entropy in open systems

Nobuyuki Okuma et al.

Summary: This study explores the roles of non-Hermitian topology in the spectral properties and entanglement structures of open systems, providing a unified understanding of quantum anomaly and non-Hermitian skin effects. By using this unified interpretation, symmetry-protected and higher-dimensional skin effects are classified. In terms of entanglement structure, the steady states of fermionic open systems with non-Hermitian topological spectra are investigated, linking them to Majorana edge modes and chiral edge states.
