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 …

Entropy production fluctuations encode collective behavior in active matter

T GrandPre, K Klymko, KK Mandadapu, DT Limmer - Physical Review E, 2021 - APS
We derive a general lower bound on distributions of entropy production in interacting active
matter systems. The bound is tight in the limit that interparticle correlations are small and …

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 …

Fluctuating motion in an active environment

C Maes - Physical Review Letters, 2020 - APS
We derive the fluctuation dynamics of a probe in weak coupling with a living medium,
modeled as particles undergoing an active Ornstein-Uhlenbeck dynamics. Nondissipative …

[HTML][HTML] Jerky active matter: a phase field crystal model with translational and orientational memory

M Te Vrugt, J Jeggle, R Wittkowski - New Journal of Physics, 2021 - iopscience.iop.org
Most field theories for active matter neglect effects of memory and inertia. However, recent
experiments have found inertial delay to be important for the motion of self-propelled …

Shape matters: a Brownian microswimmer in a channel

H Chen, JL Thiffeault - Journal of Fluid Mechanics, 2021 - cambridge.org
We consider the active Brownian particle model for a two-dimensional microswimmer with
fixed speed, whose direction of swimming changes according to a Brownian process. The …

[HTML][HTML] Motility-induced shear thickening in dense colloidal suspensions

AG Bayram, FJ Schwarzendahl, H Löwen… - Soft Matter, 2023 - pubs.rsc.org
Phase transitions and collective dynamics of active colloidal suspensions are fascinating
topics in soft matter physics, particularly for out-of-equilibrium systems, which can lead to …

[HTML][HTML] A large deviation theory perspective on nanoscale transport phenomena

DT Limmer, CY Gao, AR Poggioli - The European Physical Journal B, 2021 - Springer
Understanding transport processes in complex nanoscale systems, like ionic conductivities
in nanofluidic devices or heat conduction in low-dimensional solids, poses the problem of …

Relaxation in a phase-separating two-dimensional active matter system with alignment interaction

S Chakraborty, SK Das - The Journal of Chemical Physics, 2020 - pubs.aip.org
Via computer simulations, we study kinetics of pattern formation in a two-dimensional active
matter system. Self-propulsion in our model is incorporated via the Vicsek-like activity, ie …

Shear-induced orientational ordering in an active glass former

R Mandal, P Sollich - … of the National Academy of Sciences, 2021 - National Acad Sciences
Dense assemblies of self-propelled particles that can form solid-like states also known as
active or living glasses are abundant around us, covering a broad range of length scales …
