Extracting work from hidden degrees of freedom
Lokesh Muruga, Felix Ginot, Sarah A. M. Loos +1
Thermodynamics establishes that information acquired through measurement can be converted into work, as exemplified by Maxwell's demon and Szilard engines. Most experimental realiz…
Average negative heat in a non-Markovian bath
Felix Ginot, Clemens Bechinger
We experimentally study the motion of a colloidal particle, translated back and forth within a viscoelastic, i.e. non-Markovian bath. The particle starts in equilibrium before the…
Universal symmetry of optimal control at the microscale
Sarah A. M. Loos, Samuel Monter, Felix Ginot +1
Optimizing the energy efficiency of driving processes provides valuable insights into the underlying physics and is of crucial importance for numerous applications, from biological…
Memory-induced alignment of colloidal dumbbells
Karthika Krishna Kumar, Juliana Caspers, Félix Ginot +2
When a colloidal probe is forced through a viscoelastic fluid which is characterized by a long stress-relaxation time, the fluid is excited out of equilibrium. This is leading to a…
Memory induced Magnus effect
Xin Cao, Debankur Das, Niklas Windbacher +3
Spinning objects which move through air or liquids experience a Magnus force. This effect is commonly exploited in ball sports but also of considerable importance for applications…
How are mobility and friction related in viscoelastic fluids?
Juliana Caspers, Nikolas Ditz, Karthika Krishna Kumar +4
The motion of a colloidal probe in a viscoelastic fluid is described by friction or mobility, depending on whether the probe is moving with a velocity or feeling a force. While the…
Recoil experiments determine the eigenmodes of viscoelastic fluids
Félix Ginot, Juliana Caspers, Luis Frieder Reinalter +3
We experimentally investigate the recoil dynamics of a colloidal probe particle after shearing it with constant velocity through a viscoelastic fluid. The recoil displays two disti…
Barrier crossing in a viscoelastic bath
Félix Ginot, Juliana Caspers, Matthias Krüger +1
We investigate the hopping dynamics of a colloidal particle across a potential barrier and within a viscoelastic, i.e., non-Markovian bath, and report two clearly separated time sc…
Micro-rheology of a particle in a nonlinear bath: Stochastic Prandtl-Tomlinson model
Rohit Jain, Félix Ginot, Matthias Krüger
The motion of Brownian particles in nonlinear baths, such as, e.g., viscoelastic fluids, is of great interest. We theoretically study a simple model for such bath, where two partic…
Two step micro-rheological behavior in a viscoelastic fluid
Rohit Jain, Félix Ginot, Johannes Berner +2
We perform micro-rheological experiments with a colloidal bead driven through a viscoelastic worm-like micellar fluid and observe two distinctive shear thinning regimes, each of th…
Unveiling cells' local environment during cryopreservation by correlative in situ spatial and thermal analyses
Kankan Qin, Corentin Eschenbrenner, Felix Ginot +4
Cryopreservation is the only fully established procedure to extend the lifespan of living cells and tissues, a key to activities spanning from fundamental biology to clinical pract…
Solute effects in confined freezing
Felix Ginot, Théo Lenavetier, Dmytro Dedovets +1
The presence of liquid water in frozen media impacts the strength of soils, the growth of frost heave, plant life and microbial activities, or the durability of infrastructures in…
Nonmonotonic behavior in the dense assemblies of active colloids
Natsuda Klongvessa, Félix Ginot, Christophe Ybert +2
We study experimentally a sediment of self-propelled Brownian particles with densities ranging from dilute to ergodic supercooled, to nonergodic glass, to nonergodic polycrystal. I…
Active glass: ergodicity breaking dramatically affects response to self-propulsion
Natsuda Klongvessa, Félix Ginot, Christophe Ybert +2
We study experimentally the response of a dense sediment of Brownian particles to self-propulsion. We observe that the ergodic supercooled liquid relaxation is monotonically enhanc…
Sedimentation of self-propelled Janus colloids: polarization and pressure
Felix Ginot, Alexandre Solon, Yariv Kafri +3
We study experimentally-using Janus colloids-and theoretically-using Active Brownian Particles- the sedimentation of dilute active colloids. We first confirm the existence of an ex…
Nonequilibrium equation of state in suspensions of active colloids
Félix Ginot, Isaac Theurkauff, Demian Levis +4
Active colloids constitute a novel class of materials composed of colloidal-scale particles locally converting chemical energy into motility, mimicking micro-organisms. Evolving fa…
