In this talk, I will show our lower bound on entropy production fluctuations for interacting active matter. In general, this bound is tight when interparticle correlations are short-ranged. I will show for four different models of active matter that the bound is weak where long-ranged correlations are present near phase transitions. Furthermore, we developed theory to explain the large fluctuations that are related to these phase transitions in active Brownian particles. We also derive control forces to tune dissipation and phase behavior. These results show the connection between dissipation and pattern formation and how to control it.
