Wave topology brought to the coast
Antoine Venaille, Pierre Delplace
Since the pioneering work of Kelvin on Laplace tidal equations, a zoology of trapped waves have been found in the context of coastal dynamics. Among them, the one originally comput…
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…
Wavefront dislocations reveal the topology of quasi-1D photonic insulators
C. Dutreix, M. Bellec, P. Delplace +1
Phase singularities appear ubiquitously in wavefields, regardless of the wave equation. Such topological defects can lead to wavefront dislocations, as observed in a humongous numb…
Topological swing in Bloch oscillations
L. K. Upreti, C. Evain, S. Randoux +3
We report new oscillations of wavepackets in quantum walks subjected to electric fields, that decorate the usual Bloch-Zener oscillations of insulators. The number of turning point…
Topological chiral interface states beyond insulators
Lavi K. Upreti, P. Delplace
We show how to engineer a chiral spectral flow of interface states in a gapless system. Although the bulk bands touch -- thus making the topological indices of the bands ill-define…
