Topological effects of a vorticity filament on the coherent backscattering cone

Aubry, Geoffroy J. ; Roux, Philippe

In: Physical Review Letters, 2019, vol. 123, no. 3, p. 035503

In this Letter, we report on the effects of a vorticity filament on the coherent backscattering cone. Using ultrasonic waves in a strongly reverberating cavity, we experimentally show that the discrete number of loops of acoustic paths around a pointlike vortex located at the center of the cavity drives the cancellation and the potential rebirth of the coherent backscattering enhancement. The...
