Classical dynamical density functional theory (DDFT) is one of the cornerstones of modern
statistical mechanics. It is an extension of the highly successful method of classical density …

In microrheology, the local and bulk mechanical properties of a complex fluid are extracted
from the motion of probe particles embedded within it. In passive microrheology, particles …

Microrheology was proposed almost twenty years ago as a technique to obtain rheological
properties in soft matter from the microscopic motion of colloidal tracers used as probes …

Microscopic colloidal particles suspended in liquids are a prominent example of an
overdamped system where viscous forces dominate over inertial effects. Frequently, colloids …

We introduce active, probe-based microrheological techniques for measuring the flow and
deformation of complex fluids. These techniques are ideal for mechanical characterization …

Langevin equations or generalized Langevin equations (GLEs) are popular models for
describing the motion of a particle in a fluid medium in an effective manner. Here we …

We optically drive a trapped microscale probe through entangled DNA at rates up to 100×
the disentanglement rate (Wi≈ 100), then remove the trap and track subsequent probe …

Microrheology has emerged as a powerful approach for elucidating mechanical properties
of soft materials and complex fluids, especially biomaterials. In this technique, embedded …

When a probe particle immersed in a fluid with nonlinear interactions is subject to strong
driving, the cumulants of the stochastic force acting on the probe are nonlinear functionals of …

Optical tweezers microrheology (OTM) offers a powerful approach to probe the nonlinear
response of complex soft matter systems, such as networks of entangled polymers, over …
