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 …

Hidden velocity ordering in dense suspensions of self-propelled disks

L Caprini, UMB Marconi, C Maggi, M Paoluzzi… - Physical Review …, 2020 - APS
Recent investigations of the phase diagram of spherical, purely repulsive, active particles
established the existence of a transition from a liquidlike to a solidlike phase analogous to …

[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 …

Long-time position distribution of an active Brownian particle in two dimensions

U Basu, SN Majumdar, A Rosso, G Schehr - Physical Review E, 2019 - APS
We study the late-time dynamics of a single active Brownian particle in two dimensions with
speed v 0 and rotation diffusion constant DR. We show that at late times t≫ DR− 1, while the …

Dynamics of active particles with space-dependent swim velocity

L Caprini, UMB Marconi, R Wittmann, H Löwen - Soft Matter, 2022 - pubs.rsc.org

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 …

Unraveling hidden interactions in complex systems with deep learning

S Ha, H Jeong - Scientific reports, 2021 - nature.com
Rich phenomena from complex systems have long intrigued researchers, and yet modeling
system micro-dynamics and inferring the forms of interaction remain challenging for …

Correlated escape of active particles across a potential barrier

L Caprini, F Cecconi… - The Journal of Chemical …, 2021 - pubs.aip.org
