Non-Markovian dynamics of a torsion pendulum immersed in an active bath

Year: 2025

Type: article

Abstract: Torsion pendulums are versatile tools for exploring complex systems, including those out of equilibrium. The authors investigate macroscopic selfpropelled rod-like robots, revealing non-Markovian dynamics and exponentially correlated noise, with implications for understanding active matter and testing fluctuation theorems in dense particle assemblies.
