We study the single-file dynamics of three classes of active particles: run-and-tumble particles, active Brownian particles and active Ornstein-Uhlenbeck particles. At high activity values, the particles, interacting via purely repulsive and short-ranged forces, aggregate into several motile and dynamical clusters of comparable size, and do not display bulk phase-segregation. In this dynamical steady-state, we find that the cluster size distribution of these aggregates is a scaled function of…

Harnessing confinement and driving to tune active particle dynamics
A distinguishing feature of active particles is the nature of the non-equilibrium noise driving their dynamics. Control of these noise properties is, therefore, of both fundamental and applied
Hard core run and tumble particles on a one-dimensional lattice.
The large scale behavior of a collection of hard core run and tumble particles on a one-dimensional lattice with periodic boundary conditions is studied to calculate the hydrodynamic coefficients of diffusivity and conductivity and show that the Einstein relation is violated in both regimes.
Anomalous diffusion of self-align active particle in flow background
Active particles (i.e., self-propelled particles or called microswimmers), different from passive Brownian particles, possess more complicated translational and angular dynamics, which can generate a
Tracer dynamics in one dimensional gases of active or passive particles
We consider one-dimensional systems comprising either active run-and-tumble particles (RTPs) or passive Brownian random walkers. These particles are either noninteracting or have hardcore exclusions.
Active mixtures in a narrow channel: motility diversity changes cluster sizes.
A minimal model for bacteria in a narrow channel to assess the relative importance of motility diversity and confinement is developed and an effective theory is developed to give accurate expressions for the CSD, the effective α, and the average fraction of mobile particles.
Deterministic Active Matter Generated Using Strange Attractors
Strange attractors can be induced by governing differential or integro-differential equations associated with nonlinear dynamical systems, but they may also drive such dynamics. We outline a flexible
Dynamics of a randomly kicked particle
Lévy walk (LW) process has been used as a simple model for describing anomalous diffusion in which the mean squared displacement of the walker grows non-linearly with time in contrast to the
Heat fluctuations in a harmonic chain of active particles.
This paper studies the heat fluctuations in a system of interacting active particles, specifically a one-dimensional harmonic chain of N active Ornstein-Uhlenbeck particles, with the chain ends connected to heat baths of different temperatures.

Time-dependent properties of interacting active matter: Dynamical behavior of one-dimensional systems of self-propelled particles
We study an interacting high-density one-dimensional system of self-propelled particles described by the Active Ornstein-Uhlenbeck particle (AOUP) model where, even in the absence of alignment


Collective motion of active Brownian particles with polar alignment.
A phase diagram is established that summarizes collective behavior of polar active brownian particles and a generic mechanism to describe the complexity of the large-scale structures observed in systems of repulsive self-propelled particles is proposed.
A kinetic model and scaling properties of non-equilibrium clustering of self-propelled particles
We demonstrate that the clustering statistics and the corresponding phase transition to non-equilibrium clustering found in many experiments and simulation studies with self-propelled particles
Active brownian particles and run-and-tumble particles: A comparative study
Active Brownian particles (ABPs) and Run-and-Tumble particles (RTPs) both self-propel at fixed speed v along a body-axis u that reorients either through slow angular diffusion (ABPs) or sudden
Tagged Particle in Single-File Diffusion
Single-file diffusion is a one-dimensional interacting infinite-particle system in which the order of particles never changes. An intriguing feature of single-file diffusion is that the mean-square
Active Brownian particles escaping a channel in single file.
This work considers a minimal two-dimensional model for active Brownian particles and shows that activity conveys to self-propelled particles a strategic advantage for trespassing narrow channels against external biases (e.g., the gravitational field).
Diffusion of finite-sized hard-core interacting particles in a one-dimensional box: Tagged particle dynamics.

Universal large deviations for the tagged particle in single-file motion.
Here the exact large deviation function for the tagged particle displacement is computed and it is shown that this is universal, independent of the individual dynamics.
When are active Brownian particles and run-and-tumble particles equivalent? Consequences for motility-induced phase separation
Active Brownian particles (ABPs, such as self-phoretic colloids) swim at fixed speed v along a body-axis u that rotates by slow angular diffusion. Run-and-tumble particles (RTPs, such as motile
Steady state, relaxation and first-passage properties of a run-and-tumble particle in one-dimension
We investigate the motion of a run-and-tumble particle (RTP) in one dimension. We find the exact probability distribution of the particle with and without diffusion on the infinite line, as well as
A comparative study between two models of active cluster crystals
An effective description is developed which captures some properties of the stable clusters for both ABP and AOUP, and the different phases appearing in the system, in particular, the formation of ordered patterns drifting in space without being altered.
