Mobility-induced kinetic effects in multicomponent mixtures
Filipe C. Thewes, Matthias Krüger, Peter Sollich
We give an overview exploring the role of kinetics in multicomponent mixtures. Compared to the most commonly studied binary (single species plus solvent) case, multicomponent fluid…
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…
