Transport Properties of Active Particles Moving on Adjustable Networks
William G. C. Oropesa, P. de Castro, Hartmut Löwen +1
Active adaptive matter has attracted considerable interest due to its rich, largely unexplained dynamics and its relevance to a wide range of synthetic and biological materials. An…
Inverse engineering of cooling protocols: from normal behavior to Mpemba effects
Hartmut Löwen
When a cup of hot coffee is suddenly put into a cold environment, it cools down as a function of time until the internal temperature of the coffee equals the ext…
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…
Windmilling clusters of active quadrupoles
Margaret Rosenberg, Hartmut Löwen
Active matter has thrived in recent years, driven both by the insight that it underlies fundamental processes in nature, and by its vast potential for applications. This allows for…
Translational and Rotational Temperature Difference in Coexisting Phases of Inertial Active Dumbbells
Subhasish Chaki, Hartmut Löwen
We investigate the effect of translational and rotational inertia on motility-induced phase separation in underdamped active dumbbells and identify the emergence of four distinct k…
Anomalous grain dynamics and grain locomotion of odd crystals
Zhi-Feng Huang, Michael te Vrugt, Raphael Wittkowski +1
Crystalline or polycrystalline systems governed by odd elastic responses are known to exhibit complex dynamical behaviors involving self-propelled dynamics of topological defects w…
