Probing molecular-motor forces driving Chlamydomonas gliding motility by holographic microscopy
Nicolas Fares, Elorri Garcia, Ahmad Badr +5
The unicellular microalga Chlamydomonas reinhardtii is a widely used model microswimmer for biophysicists. However, the interest around C. reinhardtii goes beyond its swimming capa…
First-passage statistics of confined colloids
Guirec de Tournemire, Nicolas Fares, Yacine Amarouchene +1
The encounter of diffusing entities underlies a wide range of natural phenomena. The dynamics of these first-passage dynamics are strongly influenced by confining geometries. Confi…
Enhanced dispersion of active microswimmers in confined flows
Marc Lagoin, Juliette Lacherez, Guirec de Tournemire +4
In the presence of a laminar shear flow, the diffusion of passive colloidal particles is enhanced in the direction parallel to the flow. This classical phenomenon is known as Taylo…
Brownian motion near a soft surface
Yilin Ye, Yacine Amarouchene, Raphaël Sarfati +2
Brownian motion near soft surfaces is a situation widely encountered in nanoscale and biological physics. However, a complete theoretical description is lacking to date. Here, we t…
Wavefront Shaping of Scattering Forces Enhances Optical Trapping of Levitated Nanoparticles
Melissa Kleine, Michael Horodynski, Stefan Rotter +4
Optically-levitated nanoparticles in vacuum offer a pristine platform for high-quality mechanical oscillators, enabling a wide range of precision measurements and quantum technolog…
Enhanced diffusion over a periodic trap by hydrodynamic coupling to an elastic mode
Juliette Lacherez, Maxime Lavaud, Yacine Amarouchene +2
In many physical systems, degrees of freedom are coupled \emph{via} hydrodynamic forces, even in the absence of Hamiltonian interactions. A particularly important and widespread ex…
