The topological counterparts of non-Hermitian SSH models

Y. Z. Han et al.

Summary: In this study, the counterpart of the non-Hermitian SSH model was constructed to demonstrate the elimination of the non-Hermitian skin effect and the non-Hermitian Aharonov-Bohm effect under open boundary conditions. The transformation of non-Hermitian models and non-reciprocal hopping in the non-Hermitian SSH models were also discussed. Additionally, the disappearance of effective imaginary magnetic flux in the partner of the non-Hermitian SSH model was elaborated, leading to the analytical determination of topological invariants in conventional Brillouin zone.

Topological phases of the dimerized Hofstadter butterfly

Zheng-Wei Zuo et al.

Summary: This work investigates the topological phases of a dimerized square lattice in the presence of an external magnetic field. Different fractional fillings lead to the emergence of various topological phases such as the quadrupole insulator phase, obstructed atomic limit phases, and Chern insulator phases. Both bulk-obstructed and boundary-obstructed topological phase transitions are observed across the phase diagram.

Floquet graphene antidot lattices

Andrew Cupo et al.

Summary: We establish the theoretical foundation of the Floquet graphene antidot lattice and find a rich phase diagram as the drive field amplitude is varied. This study shows that the Dirac dispersion can be restored in real time, enabling the creation of optoelectronic switches or dynamically tunable electronic waveguides. Furthermore, adjusting the drive field amplitude can change the quasienergy gap and affect scattering processes relevant to electronic transport and optical emission. Additionally, selective dynamical localization and the emergence of Floquet semi-Dirac materials are observed, indicating potential for next-generation on-chip optoelectronic devices.

PT-symmetry breaking in a Kitaev chain with one pair of gain-loss potentials

Kaustubh S. Agarwal et al.

Summary: The study obtained the PT threshold for a one-dimensional, finite Kitaev chain and identified a rich phase diagram for the threshold, which can be qualitatively understood in relation to the band structure of the Hermitian Kitaev model. The findings include a re-entrant PT-symmetric phase bounded by second-order exceptional point contours for an even chain with zero on-site potential.

Two-dimensional non-Hermitian topological phases induced by asymmetric hopping in a one-dimensional superlattice

Junpeng Hou et al.

Summary: This study demonstrates the realization of two unique classes of non-Hermitian two-dimensional topological phases by solely tuning staggered non-Hermitian or asymmetric hopping strengths in a one-dimensional superlattice. These non-Hermitian topological phases support real edge modes and can coexist in a certain parameter regime. The proposed phases could be experimentally realized in photonic or atomic systems, potentially exploring new realms of non-Hermitian topological phases with 1D superlattices.

Transport and spectral features in non-Hermitian open systems

A. F. Tzortzakakis et al.

Summary: The study focuses on the transport and spectral properties of a non-Hermitian one-dimensional disordered lattice, revealing that all states in the system are localized and the eigenvalue spectrum exhibits an intricate fractallike structure on the complex plane with eigenvalue condensation. Despite Anderson localization of all eigenstates, transport in the system seems to occur through sudden jumps between states rather than diffusion, suggesting a new mechanism for open non-Hermitian random systems.

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.

Floquet second-order topological insulators in non-Hermitian systems

Hong Wu et al.

Summary: This study explores the role of periodic driving in creating exotic non-Hermitian SOTIs in 2D and 3D systems, proposing a scheme to retrieve the BBC and provide a complete description of SOTIs through the bulk topology of nonequilibrium systems. It is found that periodic driving can induce rich exotic non-Hermitian SOTIs with tunable numbers of 2D corner states and 3D hinge states, as well as a coexistence of first-and second-order topological insulators.
