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…
