Critical escape dynamics of an active particle moving on curved surfaces
Maxim Root, Hartmut Löwen, Peter Sollich +2
On the macroscopic scale, active (self-propelled) objects moving through complex environments are often subject to effects arising from both the curvature of the surrounding surfac…
Jerky Motion of Active Granular Particles
Alexander P. Antonov, Marco Musacchio, Hartmut Löwen +1
Abrupt transitions between rest and motion can render the standard Newtonian description -- based on position, velocity, and acceleration -- incomplete, requiring higher-order deri…
Quantization of the classical Mpemba effect
Jannis Melles, Hartmut Löwen, Benno Liebchen +4
The Mpemba effect refers to the counterintuitive phenomenon that an initially hot system can freeze faster than an initially warm one. Recent years have brought major advances in b…
A particle-resolved rheological study of chirality transfer and odd transport
Rémi Goerlich, Alexander P. Antonov, Kristian Stølevik Olsen +4
Chirality, or the breaking of mirror symmetry, appears across all scales in nature, from molecular conformations to the dynamics of bacterial collectives. Environments composed of…
Anomalous Mean-Squared Displacement in Quantum Active Matter from a Wigner Phase-Space Framework
Sangyun Lee, Yehor Tuchkov, Alexander P. Antonov +4
Active matter is driven out of equilibrium by a local influx of energy. While classical active matter has been extensively studied, the extension of active matter concepts to quant…
Circling crystals in chiral active matter with self-alignment
Marco Musacchio, Alexander P. Antonov, Hartmut Löwen +1
We study a crystal composed of active units governed by self-alignment and chirality. The first mechanism acts as an effective torque that aligns the particle orientation with its…
Modeling dissipation in quantum active matter
Alexander P. Antonov, Sangyun Lee, Benno Liebchen +5
Active matter is characterized by a constant influx and dissipation of energy that gives rise to directed motion. Dissipation requires interactions with an external environment, su…
Temperature overshooting in the Mpemba effect of frictional active matter
Alexander P. Antonov, Hartmut Löwen
The traditional Mpemba effect refers to an anomalous cooling phenomenon when an initial hotter system cools down faster than an initial warm system. Such counterintuitive behavior…
Flocking as a second-order phase transition in self-aligning active crystals
Marco Musacchio, Alexander P. Antonov, Hartmut Löwen +1
We study a two-dimensional crystal composed of active units governed by self-alignment. This mechanism induces a torque that aligns a particle's orientation with its velocity and l…
Self-alignment and anti-self-alignment suppress motility-induced phase separation in active systems
Marco Musacchio, Alexander P. Antonov, Hartmut Löwen +1
In this article, we investigate the impact of self-alignment and anti-self-alignment on collective phenomena in dense active matter. These mechanisms correspond to effective torque…
Self-sustained frictional cooling in active matter
Alexander P. Antonov, Marco Musacchio, Hartmut Löwen +1
Cooling processes in nature are typically generated by external contact with a cold reservoir or bath. According to the laws of thermodynamics, the final temperature of a system is…
Controlling Colloidal Flow through a Microfluidic Y-junction
Alexander P. Antonov, Matthew Terkel, Fabian Jan Schwarzendahl +3
Microscopic particles flowing through narrow channels may accumulate near bifurcation points provoking flow reduction, clogging and ultimately chip breakage. Here we show that the…
Inertial active matter with Coulomb friction
Alexander P. Antonov, Lorenzo Caprini, Anton Ldov +2
Friction is central to the motion of active (self-propelled) objects such as bacteria, animals, and robots. While in a viscous fluid friction is described by Stokes's law, objects…
Engineering active motion in quantum matter
Alexander P. Antonov, Yuanjian Zheng, Benno Liebchen +1
We introduce a framework for engineering active quantum matter that involves mimicking the role of self-propulsion through an external trapping potential that is moving along impos…
