Topologically invisible defects in chiral mirror lattices
Antonin Coutant, Li-Yang Zheng, Vassos Achilleos +3
One of the hallmark of topological insulators is having conductivity properties that are unaffected by the possible presence of defects. In this work, we go beyond backscattering i…
Acoustic Su-Schrieffer-Heeger lattice: Direct mapping of acoustic waveguides to Su-Schrieffer-Heeger model
Antonin Coutant, Audrey Sivadon, Liyang Zheng +4
Topological physics strongly relies on prototypical lattice model with particular symmetries. We report here on a theoretical and experimental work on acoustic waveguides that is d…
Topological two-dimensional Su-Schrieffer-Heeger analogue acoustic networks: Total reflection at corners and corner induced modes
Antonin Coutant, Vassos Achilleos, Olivier Richoux +2
In this work, we investigate some aspects of an acoustic analogue of the two-dimensional Su-Schrieffer-Heeger model. The system is composed of alternating cross-section tubes conne…
Robustness of topological corner modes against disorder and application to acoustic networks
Antonin Coutant, Vassos Achilleos, Olivier Richoux +2
We study the two-dimensional extension of the Su-Schrieffer-Heeger model in its higher order topological insulator phase, which is known to host corner states. Using the separabili…
