Learning Effective Hydro-Phoretic Interactions in Active Matter
Palash Bera, Aritra K. Mukhopadhyay, Benno Liebchen
In the quest to understand large-scale collective behavior in active matter, the complexity of hydrodynamic and phoretic interactions remains a fundamental challenge. To date, most…
Quantifying surfactant adsorption at fluid interfaces by combining X-ray reflectivity and simulations
Kay-Robert Dormann, Joshua Reed, Chen Shen +4
Adsorption of surfactants to fluid interfaces occurs in numerous daily-life and technological contexts. The surfactant surface coverage governs interface characteristics like…
A general model for frictional contacts in colloidal systems
Kay Hofmann, Kay-Robert Dormann, Benno Liebchen +1
In simulations of colloidal matter, frictional contacts between particles are often neglected. For spherical colloids, such an approximation can be problematic, since frictional co…
Learning microstructure in active matter
Writu Dasgupta, Suvendu Mandal, Aritra K. Mukhopadhyay +1
Understanding microstructure in terms of closed-form expressions is an open challenge in nonequilibrium statistical physics. We propose a simple and generic method that combines pa…
Automated decision-making by chemical echolocation in active droplets
Aritra K. Mukhopadhyay, Ran Niu, Linhui Fu +5
Motile microorganisms, like bacteria and algae, unify abilities like self-propulsion, autonomous navigation, and decision-making on the micron scale. While recent breakthroughs hav…
Active thermodynamics of inertial chiral active gases: equation of state and edge currents
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Benno Liebchen +1
One of the most fundamental quests in the physics of active matter concerns the existence of a comprehensive theory for its macroscopic properties, i.e. an ``active thermodynamics'…
