Fourier Plane Tomographic Spectroscopy Reveals Orientation-Dependent Multipolar Plasmon Modes in Micrometer-Scale Janus Particles
Felix H. Patzschke, Frank Cichos
Plasmonic Janus particles, comprising dielectric cores with thin metallic caps, exhibit complex optical properties due to their asymmetric structure. Despite applications in active…
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…

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…
Roadmap on Deep Learning for Microscopy
Giovanni Volpe, Carolina Wählby, Lei Tian +72
Through digital imaging, microscopy has evolved from primarily being a means for visual observation of life at the micro- and nano-scale, to a quantitative tool with ever-increasin…
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…
