Active rheology of soft solids performed with acoustical tweezers
Antoine Penneron, Thomas Brunet, Diego Baresch
Single-beam acoustical tweezers are used to manipulate individual microbubbles and provide quantitative measurements of the local shear modulus of soft hydrogels. The microbubbles…
Confined phase singularities reveal the spin-to-orbital angular momentum conversion of sound waves
Ludovic Alhaïtz, Thomas Brunet, Christophe Aristégui +2
We identify an acoustic process in which the conversion of angular momentum between its spin and orbital form takes place. The interaction between an evanescent wave propagating at…
Orbital angular momentum transfer to stably trapped elastic particles in acoustical vortex beams
Diego Baresch, Régis Marchiano, Jean-Louis Thomas
The controlled rotation of solid particles trapped in a liquid by an ultrasonic vortex beam is observed. Single polystyrene beads, or clusters, can be trapped against gravity while…
Radiative transfer of acoustic waves in continuous complex media: Beyond the Helmholtz equation
Ibrahim Baydoun, Diego Baresch, Romain Pierrat +1
Heterogeneity can be accounted for by a random potential in the wave equation. For acoustic waves in a fluid with fluctuations of both density and compressibility (as well as for e…
Observation of a single-beam gradient force acoustical trap for elastic particles: acoustical tweezers
Diego Baresch, Jean-Louis Thomas, Régis Marchiano
We demonstrate the trapping of elastic particles by the large gradient force of a single acoustical beam in three dimensions. Acoustical tweezers can push, pull and accurately cont…
Scattering mean-free path in continuous complex media: beyond the Helmholtz equation
Ibrahim Baydoun, Diego Baresch, Romain Pierrat +1
We present theoretical calculations of the ensemble-averaged (a.k.a. effective or coherent) wavefield propagating in a heterogeneous medium considered as one realization of a rando…
