Modeling active colloids: From active brownian particles to hydrodynamic and chemical fields

A Zöttl, H Stark - Annual Review of Condensed Matter Physics, 2023 - annualreviews.org
Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from
their surroundings. Here, we review the numerical and theoretical modeling of active …

Time irreversibility in active matter, from micro to macro

J O'Byrne, Y Kafri, J Tailleur, F van Wijland - Nature Reviews Physics, 2022 - nature.com
Active matter encompasses systems whose individual constituents dissipate energy to exert
propelling forces on their environment. These systems exhibit dynamical phenomena with …

Inertial self-propelled particles

L Caprini, U Marini Bettolo Marconi - The Journal of Chemical Physics, 2021 - pubs.aip.org
We study how inertia affects the behavior of self-propelled particles moving through a
viscous solvent by employing the underdamped version of the active Ornstein–Uhlenbeck …

Role of rotational inertia for collective phenomena in active matter

L Caprini, RK Gupta, H Löwen - Physical Chemistry Chemical Physics, 2022 - pubs.rsc.org
We investigate the effect of rotational inertia on the collective phenomena of underdamped
active systems and show that the increase of the moment of inertia of each particle favors …

Mechanical slowing down of network-forming phase separation of polymer solutions

J Yuan, M Tateno, H Tanaka - ACS nano, 2023 - ACS Publications
Phase separation is a fundamental phenomenon leading to spatially heterogeneous
material distribution, which is critical in nature, biology, material science, and industry. In …

[HTML][HTML] The parental active model: A unifying stochastic description of self-propulsion

L Caprini, AR Sprenger, H Löwen… - The Journal of Chemical …, 2022 - pubs.aip.org
We propose a new overarching model for self-propelled particles that flexibly generates a
full family of “descendants.” The general dynamics introduced in this paper, which we …

Spatial velocity correlations in inertial systems of active Brownian particles

L Caprini, UMB Marconi - Soft Matter, 2021 - pubs.rsc.org
Recently, it has been discovered that systems of active Brownian particles (APB) at high
density organise their velocities into coherent domains showing large spatial structures in …

Active refrigerators powered by inertia

L Hecht, S Mandal, H Löwen, B Liebchen - Physical Review Letters, 2022 - APS
We present the operational principle for a refrigerator that uses inertial effects in active
Brownian particles to locally reduce their (kinetic) temperature by 2 orders of magnitude …

Dynamics of active particles with translational and rotational inertia

AR Sprenger, L Caprini, H Löwen… - Journal of Physics …, 2023 - iopscience.iop.org
Inertial effects affecting both the translational and rotational dynamics are inherent to a
broad range of active systems at the macroscopic scale. Thus, there is a pivotal need for …

Inertia-induced nucleation-like motility-induced phase separation

J Su, H Jiang, Z Hou - New Journal of Physics, 2021 - iopscience.iop.org
Motility-induced phase separation (MIPS) is of great importance and has been extensively
researched in overdamped systems, nevertheless, what impacts inertia will bring on kinetics …
