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…
Run-and-tumble motion in a linear ratchet potential: Analytic solution, power extraction, and first-passage properties
Connor Roberts, Zigan Zhen
We explore the properties of run-and-tumble particles moving in a piecewise-linear "ratchet" potential by deriving analytic results for the system's steady-state probability densit…
Particle Entity in the Doi-Peliti and Response Field Formalisms
Marius Bothe, Luca Cocconi, Zigan Zhen +1
We introduce a procedure to test a theory for point particle entity, that is, whether said theory takes into account the discrete nature of the constituents of the system. We then…
Optimal Ratchet Potentials for Run-and-Tumble particles
Zigan Zhen, Gunnar Pruessner
Run-and-Tumble particles, mimicking the behaviour of microorganisms like E. coli, are a paradigmatic model of active matter. Due to self-propulsion, their random and undirected mot…
Entropy production in exactly solvable systems
Luca Cocconi, Rosalba Garcia-Millan, Zigan Zhen +2
The rate of entropy production by a stochastic process quantifies how far it is from thermodynamic equilibrium. Equivalently, entropy production captures the degree to which detail…
