Anomalous topological waves in strongly amorphous scattering networks
Zhe Zhang, Pierre Delplace, Romain Fleury
Topological insulators are crystalline materials that have revolutionized our ability to control wave transport. They provide us with unidirectional channels that are immune to obs…
Topological modes in stellar oscillations
Armand Leclerc, Guillaume Laibe, Pierre Delplace +2
Stellar oscillations can be of topological origin. We reveal this deep and so-far hidden property of stars by establishing a novel parallel between stars and topological insulators…
Non-Hermitian spectral flows and Berry-Chern monopoles
Lucien Jezequel, Pierre Delplace
We propose a non-Hermitian generalization of the correspondence between the spectral flow and the topological charges of band crossing points (Berry-Chern monopoles). A class of no…
Estimating bulk and edge topological indices in finite open chiral chains
Lucien Jezequel, Clément Tauber, Pierre Delplace
We develop a formalism to extend, simultaneously, the usual definition of bulk and edge indices from topological insulators to the case of a finite sample with open boundary condit…
Topological properties of Floquet winding bands in a photonic lattice
Albert F. Adiyatullin, Lavi K. Upreti, Corentin Lechevalier +6
The engineering of synthetic materials characterised by more than one class of topological invariants is one of the current challenges of solid-state based and synthetic materials.…
