Diffusive contact between randomly driven colloidal suspensions
Galor Geva, Tamir Admon, Maayan Levin +1
We study the relaxation process of two driven colloidal suspensions in diffusive contact to a steady state, similar to thermalization. We start by studying a single suspension, sub…
Nonequilibrium Probability Currents in Optically-Driven Colloidal Suspensions
Samudrajit Thapa, Daniel Zaretzky, Ron Vatash +4
In the absence of directional motion it is often hard to recognize athermal fluctuations. Probability currents provide such a measure in terms of the rate at which they enclose are…
Different anomalous diffusion regimes measured in the dynamics of tracer particles in actin networks
Maayan Levin, Golan Bel, Yael Roichman
It was previously believed that diffusion of a tracer particle in a viscoelastic material should be of the fractional Brownian motion (fBm) type. This is due to the long-term memor…
The Spatial Crossover between Far-From-Equilibrium and Near-Equilibrium Dynamics in Locally Driven Suspensions
Ilya Svetlizky, Yael Roichman
We examine the response of a quasi-two-dimensional colloidal suspension to a localized circular driving induced by optical tweezers. This approach, a microscale version of rheometr…
Kinetics of actin networks formation measured by time resolved particle-tracking microrheology
Maayan Levin, Raya Sorkin, David Pine +3
Actin is one of the most studied cytoskeleton proteins showing a very rich span of structures. It can self-assemble actively into dynamical structures that govern the mechanical pr…
Two Coupled Mechanisms Produce Fickian, yet non-Gaussian Diffusion in Heterogeneous Media
Indrani Chakraborty, Yael Roichman
Fickian yet non-Gaussian diffusion is observed in several biological and soft matter systems, yet the underlying mechanisms behind the emergence of non-Gaussianity while retaining…
