Phase separation kinetics and cluster dynamics in two-dimensional active dumbbell systems

CB Caporusso, LF Cugliandolo, P Digregorio… - Soft Matter, 2024 - pubs.rsc.org
Molecular dynamics simulations were employed to investigate the phase separation process
of a two-dimensional active Brownian dumbbell model. We evaluated the time dependence …

Escape of an active ring from an attractive surface: Behaving like a self-propelled Brownian particle

B Tang, J Gao, K Chen, TH Zhang, W Tian - Physical Review E, 2024 - APS
Escape of active agents from metastable states is of great interest in statistical and biological
physics. In this paper, we investigate the escape of a flexible active ring, composed of active …

M Semeraro, A Suma, G Negro - Entropy, 2024 - mdpi.com
In addition to providing general constraints on probability distributions, fluctuation theorems
allow us to infer essential information on the role played by temperature in heat exchange …

[CITAZIONE][C] Exploring Different Temperature Definitions for an Athermal Tracer in an Active Bath: Out-of-Equilibrium Effects and Mass Dependence

M Semeraro, A Suma, G Gonnella - Fluctuation and Noise Letters, 2024 - World Scientific
The notion of temperature in out-of-equilibrium systems is still elusive. Here, we explore
three different temperature definitions for an athermal tracer immersed in a out-of …
