Classical dynamical density functional theory: from fundamentals to applications

M te Vrugt, H Löwen, R Wittkowski - Advances in Physics, 2020 - Taylor & Francis
Classical dynamical density functional theory (DDFT) is one of the cornerstones of modern
statistical mechanics. It is an extension of the highly successful method of classical density …

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 …

Active Ornstein–Uhlenbeck model for self-propelled particles with inertia

GHP Nguyen, R Wittmann… - Journal of Physics …, 2021 - iopscience.iop.org
Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they
have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized …

[HTML][HTML] Effects of social distancing and isolation on epidemic spreading modeled via dynamical density functional theory

M Te Vrugt, J Bickmann, R Wittkowski - Nature communications, 2020 - nature.com
For preventing the spread of epidemics such as the coronavirus disease COVID-19, social
distancing and the isolation of infected persons are crucial. However, existing reaction …

[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 …

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 …

Phase coexistence of active Brownian particles

S Hermann, P Krinninger, D de Las Heras, M Schmidt - Physical Review E, 2019 - APS
We investigate motility-induced phase separation of active Brownian particles, which are
modeled as purely repulsive spheres that move due to a constant swim force with freely …

Correlated escape of active particles across a potential barrier

L Caprini, F Cecconi… - The Journal of Chemical …, 2021 - pubs.aip.org
We study the dynamics of one-dimensional active particles confined in a double-well
potential, focusing on the escape properties of the system, such as the mean escape time …

Escape rate of active particles in the effective equilibrium approach

A Sharma, R Wittmann, JM Brader - Physical Review E, 2017 - APS
The escape rate of a Brownian particle over a potential barrier is accurately described by the
Kramers theory. A quantitative theory explicitly taking the activity of Brownian particles into …
