Week 15.07.2024 – 21.07.2024

In this talk, we will present a field theoretic approach to capture the motion of an isolated Active Brownian Particle (ABP) [1]. We further add dry friction into the ABP model. Using the field theory approach, we calculate the effective diffusion coefficient in the presence of both wet and dry frictions in a perturbative way via the Green-Kubo relation [2]. We further compare the analytical result with the numerical simulation.
