Square-root-like higher-order topological states in three-dimensional sonic crystals

Zhi-Guo Geng et al.

Summary: This article introduces the concept of a three-dimensional square-root-like sonic crystal and third-order topological corner state, explaining their novel acoustic localized modes. These topological states can be controlled by manipulating the cavities at the boundaries. This study is important for exploring high-dimensional square-root topological materials and designing devices with sound trapping and acoustic sensing capabilities.

Complex-Real Transformation of Eigenenergies and Topological Edge States in Square-Root Non-Hermitian Topolectrical Circuits

Ruo-Long Zhang et al.

Summary: The physical properties of the unconventional complex-real transformation of eigenenergies and the topological properties characterized by robust edge states are investigated in the square-root non-Hermitian topolectrical circuits. The study reveals the flat bulk band capturing all imaginary eigenenergies and determining its destiny as an indicator of complex-real transformation. Additionally, the degeneracy and possible generation mechanism of the flat bulk band are explored, and the existence of robust topological edge states with non-zero real energy is hinted. The non-Bloch theorem is introduced to renovate the broken bulk-boundary correspondence, and the entire phase diagram of the system is presented.

qth-root non-Hermitian Floquet topological insulators

Longwen Zhou et al.

Summary: This study introduces a generic method for describing Floquet topological matter and applies it to obtain non-Hermitian Floquet topological insulators. The research demonstrates the presence of multiple edge and corner modes, non-Hermiticity induced fractional-quasienergy corner modes, and the coexistence of non-Hermitian skin effect with fractional-quasienergy edge states.

Square-root Floquet topological phases and time crystals

Raditya Weda Bomantara

Summary: In this study, a nontrivial method is proposed to design a square-root version of periodically driven phases, applicable in both noninteracting and interacting settings. It is found that the resulting systems exhibit richer physical phenomena compared to their original counterparts, while remaining robust against parameter imperfections.

Square-root non-Bloch topological insulators in non- Hermitian ring resonators

Zekun Lin et al.

Summary: The study investigated the topological skin effect in a ring resonator array which can be mapped into the square root of a Su-Schrieffer-Heeger (SSH) model with non-Hermitian asymmetric coupling. The square-root topological insulator inherits properties from its parent Hamiltonian, supports multiple topological edge modes, and doubles the number of band gaps compared to the original Hamiltonian. The study provides a promising approach to investigate the skin effect using ring resonators.

Realization of Second-Order Photonic Square-Root Topological Insulators

Wenchao Yan et al.

Summary: This research experimentally demonstrates second-order square-root higher-order topological insulators in photonics for the first time, revealing unique corner states on a specific platform. The observation of localized corner states in different bandgaps with characteristic phase structures provides insights into fundamental topological phenomena in systems with the coexistence of spin-1/2 and spin-1 Dirac-Weyl Fermions.

2n-root weak, Chern, and higher-order topological insulators, and 2n-root topological semimetals

A. M. Marques et al.

Summary: The concept of 2(n)-root topology has been introduced and applied in one-dimensional and two-dimensional systems. By iteratively squaring the Hamiltonians and applying different energy downshifts, decoupled models with specific topological features can be obtained. In certain cases, a 4-root version has been found in two-dimensional models, allowing for the mapping between non-Hermitian models and their Hermitian counterparts in some scenarios.

Z4 parafermion ±π/2 modes in an interacting periodically driven superconducting chain

Raditya Weda Bomantara

Summary: Researchers theoretically report the emergence of Z(4) parafermion edge modes in a periodically driven spinful superconducting chain with a modest fermionic Hubbard interaction. These exotic quasiparticles can be analytically and exactly derived at special parameter values, and show strong numerical evidence of robustness against variations in parameter values and spatial disorder. This proposal offers a pathway towards realizing parafermions without the need for fractional quantum Hall systems or complicated interactions.

One-dimensional 2n-root topological insulators and superconductors

A. M. Marques et al.

Summary: Square-root topology is a newly emerged subfield that describes a class of insulators and superconductors whose topological nature is only revealed after squaring their Hamiltonians. The concept can be generalized to 2(n)-root topological insulators and superconductors, with n as any positive integer, with their construction rules systematized. This work opens the way for extending 2(n)-root topology to higher-dimensional systems.

Matryoshka approach to sine-cosine topological models

R. G. Dias et al.

Summary: The study focuses on sine-cosine models with specific properties when squared, generating block-diagonal matrix representations with protected edge-state energy levels. By further examining models that maintain certain characteristics after multiple squaring operations, the research sheds light on the unique band structures determined by energy unit renormalizations and energy shifts.

Square-root topological phase with time-reversal and particle-hole symmetry

Tsuneya Yoshida et al.

Summary: The paper analyzes the topology of squared Hamiltonians for systems with time-reversal and particle-hole symmetry, revealing that two-dimensional systems of class CII have helical edge states due to nontrivial topology. The emergence of helical edge modes and surface states induced by the nontrivial topology of squared Hamiltonians in three dimensions is demonstrated in the toy model analysis.

Square-root topological semimetals

Tomonari Mizoguchi et al.

Summary: This study introduces topological semimetals generated by the square-root operation in two and three dimensions for tight-binding models, termed square-root topological semimetals. These semimetals exhibit topological band touching at finite energies and emergence of boundary modes. The research also shows that a decorated honeycomb (decorated diamond) model in class AIII hosts finite-energy Dirac cones (nodal lines) and demonstrates the robustness of finite-energy Dirac points in a spring-mass model.

Floquet higher-order topological insulator in a periodically driven bipartite lattice

Weiwei Zhu et al.

Summary: Floquet higher-order topological insulators (FHOTIs) are a novel topological phase that can occur in periodically driven lattices. An experimentally realistic bipartite system can host FHOTI phases and exhibit interesting phase transitions without breaking lattice symmetry. In the FHOTI phase, the lattice features corner modes at specific eigenphases that are robust against disorder.
