I’ve posted a preprint “Fluctuation-dissipation relation for branching particle systems”. The paper describes a fluctuation-dissipation relation (FDR) for branching processes that shows how fluctuations in clonal populations originating from a single ancestor encode both population growth and the dissipative structure of the single-particle dynamics. Simulations in the paper use the BranchingProcesses.jl package.
