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 …

Computational models for active matter

MR Shaebani, A Wysocki, RG Winkler… - Nature Reviews …, 2020 - nature.com
Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

Phoretic self-propulsion

JL Moran, JD Posner - Annual Review of Fluid Mechanics, 2017 - annualreviews.org
It is well-known that micro-and nanoparticles can move by phoretic effects in response to
externally imposed gradients of scalar quantities such as chemical concentration or electric …

Hydrodynamics determines collective motion and phase behavior of active colloids in quasi-two-dimensional confinement

A Zöttl, H Stark - Physical review letters, 2014 - APS
We study the collective motion of confined spherical microswimmers such as active colloids
which we model by so-called squirmers. To simulate hydrodynamic flow fields including …

Tuned, driven, and active soft matter

AM Menzel - Physics reports, 2015 - Elsevier
One characteristic feature of soft matter systems is their strong response to external stimuli.
As a consequence they are comparatively easily driven out of their ground state and out of …

Swimming in complex fluids

SE Spagnolie, PT Underhill - Annual Review of Condensed …, 2023 - annualreviews.org
We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

Fluid dynamics of squirmers and ciliated microorganisms

T Ishikawa - Annual Review of Fluid Mechanics, 2024 - annualreviews.org
The fluid dynamics of microswimmers has received attention from the fields of microbiology,
microrobotics, and active matter. Microorganisms have evolved organelles termed cilia for …

Nonlinear dynamics of a microswimmer in Poiseuille flow

A Zöttl, H Stark - Physical review letters, 2012 - APS
We study the three-dimensional dynamics of a spherical microswimmer in cylindrical
Poiseuille flow which can be mapped onto a Hamiltonian system. Swinging and tumbling …

Active suspensions and their nonlinear models

D Saintillan, MJ Shelley - Comptes Rendus Physique, 2013 - Elsevier
Active suspensions, such as suspensions of self-propelled microorganisms and related
synthetic microswimmers, are known to undergo complex dynamics and pattern formation as …

Dynamic clustering and chemotactic collapse of self-phoretic active particles

O Pohl, H Stark - Physical review letters, 2014 - APS
Recent experiments with self-phoretic particles at low concentrations show a pronounced
dynamic clustering [I. Theurkauff et al., Phys. Rev. Lett. 108, 268303 (2012) PRLTAO 0031 …
