recommendations! Published in 2024 at "Communications Physics"

DOI: 10.1038/s42005-025-02090-5

Abstract: Growth drives cellular dynamics in dense aggregates, including bacterial colonies, developing tissues, and tumors. However, its effects on other relevant activities have not received sufficient attention. Here, we investigate the underlying physical principles emerging from… read more here.

DOI: 10.1039/d2sm00772j

Abstract: The phase diagram of the phenomenon of motility-induced phase separation (MIPS) for a collection of self-propelled interacting disks over a large inertial range is explored using active Langevin dynamics simulation with particular emphasis on disk… read more here.

DOI: 10.1039/d5sm00134j

Abstract: Adding a small amount of passive (Brownian) particles to a two-dimensional dense suspension of repulsive active Brownian particles does not affect the appearance of a motility-induced phase separation into a dense and a dilute phase,… read more here.

DOI: 10.1039/d5sm00362h

Abstract: We simulate active Brownian particles (ABPs) with soft-repulsive interactions subjected to a four-roll-mill flow. In the absence of flow, this system exhibits motility-induced phase separation (MIPS). To investigate the interplay between MIPS and flow-induced mixing,… read more here.

DOI: 10.1088/1367-2630/aaccdd

Abstract: Motility-induced phase separation (MIPS) leads to cohesive active matter in the absence of cohesive forces. We present, extend and illustrate a recent generalized thermodynamic formalism which accounts for its binodal curve. Using this formalism, we… read more here.

DOI: 10.1103/b2r3-vfp9

Abstract: Self-propelled particles, like motile cells and artificial colloids, can spontaneously form macroscopic clusters. This phenomenon is called motility-induced phase separation (MIPS) and occurs even without attractive forces, provided that the self-propulsion direction fluctuates slowly. In… read more here.

DOI: 10.1103/physreve.106.l012601

Abstract: In living and engineered systems of active particles, self-propulsion induces an unjamming transition from a solid to a fluid phase and phase separation between a gas and a liquidlike phase. We demonstrate an interplay between… read more here.

DOI: 10.1103/physrevlett.132.208301

Abstract: When two active Brownian particles collide, they slide along each other until they can continue their free motion. For persistence lengths much larger than the particle diameter, the directors do not change, but the collision… read more here.
