Delayed Active Swimmer in a Velocity Landscape
Viktor Holubec, Alexander Fischer, Giovanni Volpe +1
Self-propelled active particles exhibit delayed responses to environmental changes, modulating their propulsion speed through intrinsic sensing and feedback mechanisms. This adapti…
Thermofluidic non-equilibrium assembly of reconfigurable functional structures
Desmond J. Quinn, Diptabrata Paul, Frank Cichos
Non-equilibrium assembly, driven by fluxes controllable by continuous external energy inputs, enables dynamic and reconfigurable structures. Such controlled 3D assembly is desired…
Regulated polarization of active particles in local osmotic flow fields
Lisa Rohde, Desmond J. Quinn, Diptabrata Paul +1
Regulation to a well-defined target state is a fundamental requirement for achieving reliable functionality in living systems and maintaining specific non-equilibrium states. The c…
The 2024 Motile Active Matter Roadmap
Gerhard Gompper, Howard A. Stone, Christina Kurzthaler +29
Activity and autonomous motion are fundamental aspects of many living and engineering systems. Here, the scale of biological agents covers a wide range, from nanomotors, cytoskelet…
Run-and-tumble motion of ellipsoidal microswimmers
Gordei Anchutkin, Viktor Holubec, Frank Cichos
A hallmark of bacteria is their so-called "run-and-tumble" motion, consisting of a sequence of linear directed "runs" and random rotations that constantly alternate due to biochemi…
Harnessing Synthetic Active Particles for Physical Reservoir Computing
Xiangzun Wang, Frank Cichos
The processing of information is an indispensable property of living systems realized by networks of active processes with enormous complexity. They have inspired many variants of…
Active particles with delayed attractions form quaking crystallites
Pin-Chuan Chen, Klaus Kroy, Frank Cichos +2
Perception-reaction delays have experimentally been found to cause a spontaneous circling of microswimmers around a targeted center. Here we investigate the many-body version of th…
Spontaneous vortex formation by microswimmers with retarded attractions
Xiangzun Wang, Pin-Chuan Chen, Klaus Kroy +2
Collective states of inanimate particles self-assemble through physical interactions and thermal motion. Despite some phenomenological resemblance, including signatures of critical…
Hydrodynamic Manipulation of Nano-Objects by Thermo-Osmotic Flows
Martin Fränzl, Frank Cichos
The manipulation of micro- and nano-objects is of great technological significance to construct new materials, manipulate tiny amounts of liquids in fluidic systems, or detect minu…
Finite-size scaling at the edge of disorder in a time-delay Vicsek model
Viktor Holubec, Daniel Geiss, Sarah A. M. Loos +2
Living many-body systems often exhibit scale-free collective behavior reminiscent of thermal critical phenomena. But their mutual interactions are inevitably retarded due to inform…
Thermotaxis of Janus Particles
Sven Auschra, Andreas Bregulla, Klaus Kroy +1
The interactions of autonomous microswimmers play an important role for the formation of collective states of motile active matter. We study them in detail for the common microswim…
Polarization-Density Patterns of Active Particles in Motility Gradients
Sven Auschra, Viktor Holubec, Nicola Andreas Söker +2
The co-localization of density modulations and particle polarization is a characteristic emergent feature of motile active matter in activity gradients. It can therefore play the r…
Active-Particle Polarization Without Alignment Forces
Nicola Andreas Söker, Sven Auschra, Viktor Holubec +2
Active-particle suspensions exhibit distinct polarization-density patterns in activity landscapes, even without anisotropic particle interactions. Such polarization without alignme…
Convolutional Neural Networks for Real-Time Localization and Classification in Feedback Digital Microscopy
Martin Fränzl, Frank Cichos
We present an adapted single-shot convolutional neural network (YOLOv2) for the real-time localization and classification of particles in optical microscopy. As compared to previou…
The 2019 Motile Active Matter Roadmap
Gerhard Gompper, Roland G. Winkler, Thomas Speck +34
Activity and autonomous motion are fundamental in living and engineering systems. This has stimulated the new field of active matter in recent years, which focuses on the physical…
Hot Microswimmers
Klaus Kroy, Dipanjan Chakraborty, Frank Cichos
Hot microswimmers are self-propelled Brownian particles that exploit local heating for their directed self-thermophoretic motion. We provide a pedagogical overview of the key physi…
Reinforcement Learning of Artificial Microswimmers
Santiago Muiños-Landin, Keyan Ghazi-Zahedi, Frank Cichos
The behavior of living systems is based on the experience they gained through their interactions with the environment [1]. This experience is stored in the complex biochemical netw…
Active Particles Bound by Information Flows
Utsab Khadka, Viktor Holubec, Haw Yang +1
Self-organization is the generation of order out of local interactions in non-equilibrium [1]. It is deeply connected to all fields of science from physics, chemistry to biology wh…
