Microscopic theory of soft run-and-tumble particles
Rosalba Garcia-Millan, Ziluo Zhang, Luca Cocconi +4
Soft, repulsive run-and-tumble particles display emergent effective interactions as they appear to stick to each other in spite of the absence of attractive forces. This effective…
Effective attraction by repulsion
Rosalba Garcia-Millan, Luca Cocconi, Ziluo Zhang +4
Repulsive self-propelled particles tend to cluster, leading to Motility-Induced Phase Separation (MIPS). By analogy with equilibrium phase separation, the onset of MIPS has been as…
Numerical investigation of the Brownian Potts Model
Letian Chen, Gunnar Pruessner
In active matter, such as the Vicsek Model of flocking, particles possesses an internal degree of freedom, such as their director, which is subject to interaction with other partic…
Correlation, crossover and broken scaling in the Abelian Manna Model
Letian Chen, Hoai Nguyen Huynh, Gunnar Pruessner
The role of correlations in self-organised critical (SOC) phenomena is investigated by studying the Abelian Manna Model (AMM) in two dimensions. Local correlations of the debris le…
