This gives rise to interesting collective effects that are not seen in systems at thermal equilibrium, such as motility induced phase separation, a hallmark of active matter. Indeed, there is great potential in harnessing the striking phenomenology of active matter to build controllable, and novel, responsive materials. Despite this potential, we currently lack a physical framework that predicts the best protocol for driving active systems between different states in a way that is thermodynamically efficient, by minimizing the dissipated heat for example. Existing equilibrium thermodynamics is an inadequate foundation to build a framework of control for active systems, due to the growing dissipation arising from the constant burning of fuel. Here, we derive and implement a novel thermodynamic control framework for active matter, using stochastic thermodynamics and response theory, to perform efficient control of continuous- and discrete-state active systems.
