We derived a simple analytical expression for the migration velocity and — without any fitting parameter — it matches experiments beautifully.

Now add rotation. The particle spins inside this asymmetric viscosity field, producing a fore–aft stress imbalance leading to a net force. Since the particle is force-free, it needs to migrate laterally to balance this force. No inertia. No normal stresses. Just microstructure + viscosity gradients.

The missing ingredient? 👉 Stress‑gradient‑induced polymer migration. At micron scales, polymers move in response to stress gradients. A translating colloid creates a fore–aft stress imbalance → polymers accumulate in front and deplete behind → a viscosity dipole forms.

Sharing a PhD advert on a very cool project on cells interacting with bacteria, which is offered by a colleague from our institute!

Being passionate about soft matter means getting excited when you find a license plate with the Boltzmann constant multiplying the absolute temperature

Very happy to be at the Annual European Rheology Conference with my group. If you are around check out our talks!

Phd opening in our lab! We are looking for a PhD student to work on simulation of active micr/nano robots. Dradline for apllication 4th of april. This is a fully funded three-years position and it is part of the MSCA Doctoral Network @dn-greens.bsky.social

This is how I found our table this morning. Anybody knows if this is really a log(x) behavior, and, if yes, why?

This was a signature of a drastic increase in the rotational diffusion coefficient compared to its value at equilibrium. We found up to five orders of magnitude increase as the Janus particle speed increases :O :O

When we included thermal fluctuations of the Janus probe and of the concentration of the complex fluid we observed trajectories progressively more curved as the particle speed increased.

These two simple mechanisms were able to explain the spontaneous onset of an angular speed beyond a critical Pèclet number.
