Second and third harmonic generation of acoustic waves in a nonlinear elastic solid in one space dimension
Fernando Lund
The generation of second and third harmonics by an acoustic wave propagating along one dimension in a weakly nonlinear elastic medium that is loaded harmonically in time with frequ…
Ultrasound scattering and the study of vortex correlations in disordered flows
Denis Boyer, Fernando Lund
In an idealized way, some turbulent flows can be pictured by assemblies of many vortices characterized by a set of particle distribution functions. Ultrasound provide an useful, no…
Scattering of dislocated wavefronts by vertical vorticity and the Aharonov-Bohm effect I: Shallow water
Christophe Coste, Makoto Umeki, Fernando Lund
When a surface wave interacts with a vertical vortex in shallow water the latter induces a dislocation in the incident wavefronts that is analogous to what happens in the Aharonov-…
Elastic forces that do no work and the dynamics of fast cracks
Fernando Lund
Elastic singularities such as crack tips, when in motion through a medium that is itself vibrating, are subject to forces orthogonal to the direction of motion and thus impossible…
Scattering of second sound waves by quantum vorticity
Fernando Lund, Victor Steinberg
A new method of detection and measurement of quantum vorticity by scattering second sound off quantized vortices in superfluid Helium is suggested. Theoretical calculations of the…
