Topology of shallow-water waves on the rotating sphere
Nicolas Perez, Armand Leclerc, Guillaume Laibe +1
Topological properties of the spectrum of shallow-water waves on a rotating spherical body are established. Particular attention is paid to its spectral flow, i.e. the modes whose…
From ray tracing to waves of topological origin in continuous media
Antoine Venaille, Yohei Onuki, Nicolas Perez +1
Inhomogeneous media commonly support a discrete number of wave modes that are trapped along interfaces defined by spatially varying parameters. When they are robust against continu…
Unidirectional modes induced by nontraditional Coriolis force in stratified fluids
Nicolas Perez, Pierre Delplace, Antoine Venaille
Using topology, we unveil the existence of new unidirectional modes in compressible rotating stratified fluids. We relate their emergence to the breaking of time-reversal symmetry…
Manifestation of Berry curvature in geophysical ray tracing
Nicolas Perez, Pierre Delplace, Antoine Venaille
Geometrical phases, such as the Berry phase, have proven to be powerful concepts to understand numerous physical phenomena, from the precession of the Foucault pendulum to the quan…
