Particles that exhibit a mechanism to convert free energy into directed propulsion are known as Active Brownian Particles (ABPs). ABPs are a nonequilibrium generalization of Brownian motion and, at sufficient propulsion strengths, show a motility-induced phase separation that resembles a gas-liquid transition in equilibrium. Understanding the stochastic thermodynamics of ABPs systems has been an important topic in recent years. In this talk, we will derive the Langevin equation for such a particle and the corresponding Fokker-Plank equation. We will also develop an analytical framework for predicting motility-induced phase separation.
