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…

Nonlinear microrheology with time-dependent forces -- Application to recoils in viscoelastic fluids
Nikolas Ditz, Antonio M. Puertas, M. Fuchs
This work presents a theoretical analysis of the motion of a tracer colloid driven by a time-dependent force through a viscoelastic fluid. The recoil of the colloid after applicati…
