C Bechinger, R Di Leonardo, H Löwen… - Reviews of modern …, 2016 - APS
Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

Chirality in microswimmer motion: From circle swimmers to active turbulence

H Löwen - The European Physical Journal Special Topics, 2016 - Springer
In this minireview, recent progress in our understanding of the basic physical principles of
microswimmers which perform a motion characterized by chirality is summarized. We …

Chiral active matter

B Liebchen, D Levis - Europhysics Letters, 2022 - iopscience.iop.org
Chiral active matter comprises particles which can self-propel and self-rotate. Examples
range from sperm cells and bacteria near walls to autophoretic L-shaped colloids. In this …

Gravitaxis of asymmetric self-propelled colloidal particles

B Ten Hagen, F Kümmel, R Wittkowski, D Takagi… - Nature …, 2014 - nature.com
Many motile microorganisms adjust their swimming motion relative to the gravitational field
and thus counteract sedimentation to the ground. This gravitactic behaviour is often the …

Time-dependent inertia of self-propelled particles: The Langevin rocket

AR Sprenger, S Jahanshahi, AV Ivlev, H Löwen - Physical Review E, 2021 - APS
Many self-propelled objects are large enough to exhibit inertial effects but still suffer from
environmental fluctuations. The corresponding basic equations of motion are governed by …

Role of tensorial electronic friction in energy transfer at metal surfaces

M Askerka, RJ Maurer, VS Batista, JC Tully - Physical review letters, 2016 - APS
An accurate description of nonadiabatic energy relaxation is crucial for modeling atomistic
dynamics at metal surfaces. Interfacial energy transfer due to electron-hole pair excitations …

Self-propelling colloids with finite state dynamics

S van Kesteren, L Alvarez… - Proceedings of the …, 2023 - National Acad Sciences
Endowing materials with the ability to sense, adapt, and respond to stimuli holds the key to a
progress leap in autonomous systems. In spite of the growing success of macroscopic soft …

[HTML][HTML] Brownian dynamics of confined rigid bodies

S Delong, F Balboa Usabiaga, A Donev - The Journal of chemical …, 2015 - pubs.aip.org
We introduce numerical methods for simulating the diffusive motion of rigid bodies of
arbitrary shape immersed in a viscous fluid. We parameterize the orientation of the bodies …

Active colloidal molecules

H Löwen - Europhysics Letters, 2018 - iopscience.iop.org
Like ordinary molecules are composed of atoms, colloidal molecules consist of several
species of colloidal particles tightly bound together. If one of these components is self …

Initiating revolutions for optical manipulation: the origins and applications of rotational dynamics of trapped particles

GD Bruce, P Rodríguez-Sevilla… - Advances in Physics …, 2021 - Taylor & Francis
The fastest-spinning man-made object is a tiny dumbbell rotating at 5 GHz. The smallest
wind-up motor is constructed from a DNA molecule. Picoliter volumes of fluids are remotely …
