Dirac cones are essential features of the electronic band structure of materials like graphene and topological insulators (TIs). Lately, this avenue has found a growing interest in classical …
A finite one-dimensional Su-Schrieffer-Heeger (SSH) chain exhibits “zero-energy” boundary- mode solutions that are protected by chiral symmetry. The breaking of chiral symmetry leads …
Topological band theory strongly relies on prototypical lattice models with particular symmetries. We report here on a theoretical and experimental work on acoustic waveguides …
Over the past several years, a new generation of quantum simulations has greatly expanded our understanding of charge density wave phase transitions in Hamiltonians with coupling …
The goal of this paper is to advance the development of wave-guiding subwavelength crystals by developing designs whose properties are stable with respect to imperfections in …
The Su-Schrieffer-Heeger (SSH) model, with bond phonons modulating electron tunneling, is a paradigmatic electron-phonon model that hosts an antiferromagnetic order to bond …

One-dimensional Su-Schrieffer-Heeger (SSH) chains are one of the simplest topological models and have been studied extensively. The two-dimensional (2 D) version has been …
Recently, we have introduced [AM Marques, Phys. Rev. B 103, 235425 (2021) 2469-9950 10.1103/PhysRevB. 103.235425] the concept of 2 n-root topology and applied it to one …
We study the rich properties of a topolectrical (TE) circuit array consisting of lossless basic electrical components, such as capacitors and inductors, which can be designed to exhibit …
