Inertial self-propelled particles

Lorenzo Caprini et al.

Summary: This study investigates how inertia affects the behavior of self-propelled particles moving through a viscous solvent using the underdamped version of the active Ornstein-Uhlenbeck model. The research reveals marked equal-time correlations between velocity and active force in the non-equilibrium steady state, and shows that inertia also impacts the time-dependent properties of active particles. Additionally, the study examines how the virial pressure of particles changes as one transitions from the overdamped to the underdamped regime, and extends the analysis of correlations in the underdamped regime to a chain of active particles interacting via harmonic springs.

Fluctuation-Dissipation Relations in Active Matter Systems

Lorenzo Caprini et al.

Summary: The study investigates the non-equilibrium nature of self-propelled particles through the linear response of the active Ornstein-Uhlenbeck particle (AOUP) model. The linear response is expressed in terms of correlations computed in the absence of perturbations, with a proposed fluctuation-dissipation relation (FDR) that separates equilibrium and non-equilibrium contributions. The case study of non-interacting AOUP confined in single-well and double-well potentials reveals the impact of dimensionality on the non-equilibrium relaxation process, highlighting the roles of position and velocity variables.

Fluctuation-dissipation relations in the absence of detailed balance: formalism and applications to active matter

Sara Dal Cengio et al.

Summary: The study examines the breakdown of detailed balance in non-equilibrium systems and its connection to violations of the fluctuation-dissipation theorem. By establishing general constraints on non-equilibrium steady-states, the research provides a unified approach to deriving extended fluctuation-dissipation relations and understanding the departure from equilibrium in active systems and their linear response. By analyzing paradigmatic models of interacting self-propelled particles, the research clarifies the genuinely non-equilibrium features of these systems and derives extended fluctuation-dissipation relations for them.

Surfactants and rotelles in active chiral fluids

Christian Scholz et al.

Summary: This study explores the behavior of active analogs of surfactants in active chiral fluids, which operate far from equilibrium and exhibit amphiphilic properties different from molecular surfactants due to their activity. By utilizing printed vibrots in experiments, researchers demonstrate the formation of spinning vesicles at interfaces, serving as mixing agents in the chiral fluid.

Crossover behaviours exhibited by fluctuations and correlations in a chain of active particles

Prashant Singh et al.

Summary: The study examines the motion of tagged particles in a harmonic chain of active particles, considering three different active particle dynamics models. It demonstrates a crossover in mean squared displacement from super-diffusive to sub-diffusive scaling and explains it with appropriate crossover functions. Furthermore, interesting scaling forms of equal and unequal time autocorrelation and cross-correlations are found in appropriate limits of observation time.

Whirligig beetles as corralled active Brownian particles

Harvey L. Devereux et al.

Summary: The study on collective dynamics of whirligig beetles swimming on water surface revealed density-dependent speed scaling, inertial delay for velocity alignment, and coexisting high and low-density phases, consistent with motility-induced phase separation theory. By modifying a model, the researchers successfully explained the co-occurrence of high- and low-density phases observed in the data.
