Fluctuating hydrodynamics in diffusive systems, the Wasserstein geometry, and hyperuniform active states.
Fluctuating hydrodynamics is a theory for fluids on large length and time scales. Here we discuss two aspects of large deviations in this limit. First, we discuss a geometrical interpretation of the action function that specifies the probability of rare trajectories [1]. Second, we discuss the nature of long-ranged correlations in a particular set of rare trajectories [2]. [1] RL Jack and J Zimmer, arXiv:1407.1679.
