Single-file transport, where particles cannot bypass each other, has been observed in various experimental setups. In such systems, the behaviour of a tracer particle (TP) is subdiffusive, which originates from strong correlations between particles. These correlations are especially marked when the TP is driven and leads to inhomogeneous density profiles. Determining the impact of this inhomogeneity when several TPs are driven in the system is a key question, related to the general issue of…

The mean-field approximation is applied to analytically explore the mechanism responsible for the tracers' emergent interactions and compute the resulting effective attractive potential, which is then numerically shown to extend to a realistic model of hard driven Brownian disks confined to a narrow 2D channel.

This analysis reveals several new features of the dynamical behaviour that are overlooked in the studies based on the Fick-Jacobs approach, in particular, trajectories passing through a funnel concentrate predominantly on its boundary, which makes first-crossing events very sensitive to the presence of binding sites and microscopic roughness.

Because active particles break time-reversal symmetry, an active fluid can sustain currents even without an external drive. We show that when a passive body is placed in a fluid of pairwise…

It is shown that the probes can either move as a whole, or separate into two groups moving away from each other, in between the two regimes, which occurs in several continuous single-file systems and is expected to be observable.

A particle driven by an external force in a molecular crowding environment—a quiescent bath of other particles, makes their spatial distribution inhomogeneous: the bath particles accumulate in front…

This work determines the correlations between pair correlation functions using an analytical approach based on a linearization of the stochastic equations for the density fields, which is valid for dense systems of soft particles and has a self-similar exponential profile in the transverse direction.

A theoretical framework that allows analytical calculation of two-tag correlations is presented on the basis of the Dean-Kawasaki equation describing density fluctuations in colloidal systems, which can be extended to the case of nonlinear fluctuations by means of closure approximation for the vacancy field.

This work introduces a novel type of locally driven systems made of two types of particles subject to a chaotic drive with approximately white noise spectrum, but different intensity; in other words, particles of different types are in contact with thermostats at different temperatures.
