Recently, trapped-particle experiments have probed the instantaneous velocity of Brownian motion revealing that, at early times, hydrodynamic history forces dominate Stokes damping. In these experiments, nonuniform particle motion is well described by the Basset-Boussinesq-Oseen (BBO) equation, which captures the unsteady Basset history force at a low Reynolds number. Building off of these results, earlier we showed that, at low temperature, BBO particles could exploit fluid inertia in order to…

The slow power law decay of the velocity autocorrelation function of a particle moving stochastically in a condensed-phase fluid is widely attributed to the momentum that fluid molecules displaced by

Introducing Memory in Coarse-Grained Molecular Simulations

This Review focuses on the construction and simulation of dynamically consistent systematic CG models based on the GLE, both in the simple Markovian limit and the non-Markovian case.

Effect of Basset’s hereditary force on bubble dynamics in liquid oxide-based diffusion-bubbling membranes

Innovative liquid oxide-based diffusion-bubbling membranes are a key perspective for efficient oxygen separation from air. The oxygen bubble motion in these membranes is usually described within the

Single-file diffusion in a bi-stable potential: Signatures of memory in the barrier-crossing of a tagged-particle.

It is found that the higher the barrier, the stronger the memory effects are, and the fact that the external potential alters the memory is important more generally and should be taken into account in applications of generalized Langevin equations.

Hydrodynamic interaction facilitates the unsteady transport of two neighboring vesicles.

The result suggests that the unsteady transport of the vesicle by molecular motors in vivo may be facilitated due to an effective hydrodynamic interaction between the neighboring vesicles.

Long-time persistence of hydrodynamic memory boosts microparticle transport

In a viscous fluid, the past motion of an accelerating particle is retained as an imprint on the vorticity field, which decays slowly as t−3/2. At low Reynolds number, the Basset-Boussinesq-Oseen

Enhanced Transport of Two Spheres in Viscous Fluid

We obtain a numerical solution for the synchronous motion of two spheres moving in viscous fluid. We find that for a given amount of work performed, the final distance travelled by each sphere is

Contributions to Non‐Equilibrium Thermodynamics. I. Theory of Hydrodynamical Fluctuations

The velocity of a particle in Brownian motion as described by the Langevin equation is a stationary Gaussian–Markov process. Similarly, in the formulation of the laws of non‐equilibrium

Eigenvalues and their connection to transition rates for the Brownian motion in an inclined cosine potential

For certain parameters the motion of particles in an inclined cosine potential is bistable, i.e. particles are either in a locked or a running state. Fluctuations will cause transitions between these
