There is some theory connecting Langevin equations to eliminated degrees of freedom (see Kubo's "Statistical Mechanics II or the classic papers by Mori), but I have not seen this used in context of active matter. You may look in the appendix here arxiv.org/pdf/cond-mat/0310384.pdf for a more "from-scratch" derivation of an active matter model | |

| Sep 30, 2017 at 23:28 | comment | added | a06e | I have read a couple of models of active systems, usually involving Langevin equations, for example to model the cytoplasm, or swarms of bacteria. But I have not found yet a single derivation of the equations of an active system in these contexts, starting from clear and well founded physical assumptions. Rather, they just assume the form of the Langevin equation from the start, or borrow from popular models used in other fields. For me, it is not obvious why the particles in these systems should receive a random force push, instead of a random energy unit. | |
