In this Letter, an elastic twisted kagome lattice at a critical twist angle, called self-dual kagome lattice, is shown to exhibit peculiar finite-frequency topological modes which emerge when certain conditions are satisfied. These states are topologically reminiscent to the zero energy (floppy) modes of Maxwell lattices but they occur at a finite frequency in the band gap of self-dual kagome lattice. Thus, we present a completely new class of topological modes which share similarities with both…

Duality, Hidden Symmetry and Dynamic Isomerism in 2D Hinge Structures

Recently, a new type of duality was reported in some deformable mechanical networks which exhibit Kramers-like degeneracy in phononic spectrum at the self-dual point. In this work, we clarify the

Existence of corner modes in elastic twisted kagome lattices

This Letter investigates the emergence of corner modes in elastic twisted Kagome lattices at a critical twist angle, known as self-dual point. We show that a special type of corner modes exist and

Edge Modes and Asymmetric Wave Transport in Topological Lattices: Experimental Characterization at Finite Frequencies.

TLDR
A systematic, laser-assisted experimental characterization of topological kagome lattices aimed at elucidating their in-plane phononic and topological characteristics, which provides unequivocal evidence of the existence of strong asymmetric wave transport regimes at finite frequencies.

Periodic table for topological insulators and superconductors

Gapped phases of noninteracting fermions, with and without charge conservation and time-reversal symmetry, are classified using Bott periodicity. The symmetry and spatial dimension determines a

Acoustic higher-order topological insulator on a kagome lattice

TLDR
A second-order topological insulator in an acoustical metamaterial with a breathing kagome lattice, supporting one-dimensional edge states and zero-dimensional corner states is demonstrated, and shape dependence allows corner states to act as topologically protected but reconfigurable local resonances.

Surface phonons, elastic response, and conformal invariance in twisted kagome lattices

TLDR
Elasticity and phonons of a special class of two-dimensional isostatic lattices constructed by distorting the kagome lattice are explored and it is shown that the phonon structure of these lattices, characterized by vanishing bulk moduli and thus negative Poisson ratios, depends sensitively on boundary conditions and on the nature of the k Kagome distortions.

Continuum Theory for Topological Edge Soft Modes.

TLDR
A topological elasticity theory for general continuous media where a gauge-invariant bulk topological index independent of microscopic details is defined, and it naturally extends to media that deviate from the Maxwell point.

Symmetry of the phononic landscape of twisted kagome lattices across the duality boundary

In this Rapid Communication, we investigate the symmetry of the phonon landscape of twisted kagome lattices across their duality boundary. The study is inspired by recent work by Fruchart et al.

Topological Phononic Crystals with One-Way Elastic Edge Waves.

TLDR
A new type of phononic crystals with topologically nontrivial band gaps for both longitudinal and transverse polarizations, resulting in protected one-way elastic edge waves, which could potentially lead to the design of a novel class of surface wave devices that are widely used in electronics, telecommunication, and acoustic imaging.

Elastic quantum spin Hall effect in kagome lattices

A Quantum Spin-Hall Insulator (QSHI) is implemented into a simple mass-spring Kagome lattice. The transition from the trivial state to the topological one is described by an invariant Chern number
