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…

Attraction and condensation of driven tracers in a narrow channel.

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.

Field-driven tracer diffusion through curved bottlenecks: fine structure of first passage events.

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.

Driven tracers in a one-dimensional periodic hard-core lattice gas

Totally asymmetric tracer particles in an environment of symmetric hard-core particles on a ring are studied. Stationary state properties, including the environment density profile and tracer

Bodies in an interacting active fluid: far-field influence of a single body and interaction between two bodies

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

Tracer diffusion on a crowded random Manhattan lattice

Numerical data convincingly demonstrate that in presence of a crowded environment the central Gaussian part and non-Gaussian tails of the distribution persist for both models.

Time-dependence of the effective temperatures of a two-dimensional Brownian gyrator with cold and hot components

We consider a model of a two-dimensional molecular machine—called Brownian gyrator—that consists of two coordinates coupled to each other and to separate heat baths at temperatures respectively T x



Unbinding Transition of Probes in Single-File Systems.

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.

Active transport in dense diffusive single-file systems.

We study a minimal model of active transport in crowded single-file environments which generalizes the emblematic model of single-file diffusion to the case when the tracer particle (TP) performs

Bias- and bath-mediated pairing of particles driven through a quiescent medium

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

Cooperative behavior of biased probes in crowded interacting systems.

The size-distribution of the self-assembling clusters in the steady-state, their specific force-velocity relations and also properties of the effective interactions emerging between the BPs are analysed.

Universal Long Ranged Correlations in Driven Binary Mixtures.

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.

Two-tag correlations and nonequilibrium fluctuation–response relation in ageing single-file diffusion

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.

Correlation and fluctuation in a random average process on an infinite line with a driven tracer

We study the effect of a single biased tracer particle in a bath of other particles performing the random average process (RAP) on an infinite line. We focus on the long time behavior of the mean and

The correlations between the positions of tagged particles in the random average process, an interacting particle system in one dimension, are studied analytically and sigma(2)(r)(t), the mean-squared fluctuation in the position difference of two tagged particles separated by a fixed tag shift r in the steady state is computed.

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.

The out of equilibrium response function in sub-diffusive systems

We study the Einstein relation between spontaneous fluctuations and the response to an external perturbation for the comb model and the single file, which are examples of systems with sub-diffusive
