In superconductivity, electrons form Cooper Pairs. This is achieved not via direct interaction but through medium (lattice) mediation. A similar thing is happening in Jeremie's experiment: swimmers deplete the medium around them, leading to attractive interactions and clustering behaviour (section \ref{sec:cluster}).  {\bf  My idea: idea}:  is the formalism for Cooper Pair formation applicable in any way to interactions of active particles? It could be an alternative way of thinking about things. Define a ``field'' representing concentration. This will have creation and annihilation operators etc. Differences:  \begin{itemize}
