The Exceptional Ring of buoyancy instability in stars
Armand Leclerc, Lucien Jezequel, Nicolas Perez +3
We reveal properties of global modes of linear buoyancy instability in stars, characterised by the celebrated Schwarzschild criterion, using non-Hermitian topology. We identify a r…
Bulk-Edge Correspondence Recovered in Incompressible Geophysical Flows
Yohei Onuki, Antoine Venaille, Pierre Delplace
Bulk-edge correspondence is a cornerstone in topological physics, establishing a connection between the number of unidirectional edge modes in physical space and a Chern number, an…
Edge-dependent anomalous topology in synthetic photonic lattices subject to discrete step walks
Rabih El Sokhen, Álvaro Gómez-León, Albert F. Adiyatullin +3
Anomalous topological phases, where edge states coexist with topologically trivial Chern bands, can only appear in periodically driven lattices. When the driving is smooth and cont…
Mode-Shell correspondence, a unifying phase space theory in topological physics -- Part I: Chiral number of zero-modes
Lucien Jezequel, Pierre Delplace
We propose a theory, that we call the \textit{mode-shell correspondence}, which relates the topological zero-modes localised in phase space to a \textit{shell} invariant defined on…
