If you have a question about this talk, please contact Professor Mike Cates. Active motility is present in some non-equilibrium particle systems where energy is transformed into self-propulsion. The entropy production rate, which crucially depends on the microscopic dynamics, measures how far from equilibrium the particle system is. In the absence of an exact solution, a microscopic theory can be provided by the Doi-Peliti formalism, where the degree of freedom is the position-wise occupation number and which is able to maintain the particle entity. To illustrate this point, I will show how to derive the Doi-Peliti field theory of a particle undergoing run-and-tumble motion with diffusion in a 1D harmonic potential, and use it to calculate the entropy production rate in closed form.
