Computational models for active matter [PDF]

Nature Reviews Physics, 2020
A variety of computational models have been developed to describe active matter at different length and time scales. The diversity of the methods and the challenges in modeling active matter---ranging from molecular motors and cytoskeletal filaments over artificial and biological swimmers on microscopic to groups of animals on macroscopic scales ...

Swirlonic state of active matter. [PDF]

Sci Rep, 2020
AbstractWe report a novel state of active matter—a swirlonic state. It is comprised of swirlons, formed by groups of active particles orbiting their common center of mass. These quasi-particles demonstrate a surprising behavior: In response to an external load they move with a constant velocity proportional to the applied force, just as objects in ...

The 2020 motile active matter roadmap

, 2020
Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of 'active matter' in recent years, which focuses on the physical aspects of propulsion mechanisms, and on motility-induced emergent ...

Configurational entropy and effective temperature in systems of active Brownian particles [PDF]

, 2016
We propose a method to determine the effective density of states and configurational entropy in systems of active Brownian particles by measuring the probability distribution function of potential energy at varying temperatures. Assuming that the entropy

Flowing Matter [PDF]

, 2019
This open access book, published in the Soft and Biological Matter series, presents an introduction to selected research topics in the broad field of flowing matter, including the dynamics of fluids with a complex internal structure -from nematic fluids ...

Optimal escapes in active matter. [PDF]

Eur Phys J E Soft Matter
Abstract The out-of-equilibrium character of active particles, responsible for accumulation at boundaries in confining domains, determines not-trivial effects when considering escape processes. Non-monotonous behavior of exit times with respect to tumbling rate (inverse of mean persistent time) appears, as a consequence

Collective motion in active matter [PDF]

Active matter is the study of collective motion of systems of particles that are able to consume energy in order to perform systematic motion. Such systems are abundant in nature and come on a large range of scales: from animal herds and bird flocks ...

Removing grain boundaries from three-dimensional colloidal crystals using active dopants [PDF]

, 2016
Using computer simulations we explore how grain boundaries can be removed from three-dimensional colloidal crystals by doping with a small fraction of active colloids.

Effective temperature of active matter [PDF]

Physical Review E, 2008
We follow the dynamics of an ensemble of interacting self-propelled motorized particles in contact with an equilibrated thermal bath. We find that the fluctuation-dissipation relation allows for the definition of an effective temperature that is compatible with the results obtained using a tracer particle as a thermometer.

Dynamics of topological defects in the noisy Kuramoto model in two dimensions

Frontiers in Physics, 2022
We consider the two-dimensional (2D) noisy Kuramoto model of synchronization with short-range coupling and a Gaussian distribution of intrinsic frequencies, and investigate its ordering dynamics following a quench. We consider both underdamped (inertial)
