What is it about?

We introduce an effective temperature for active colloidal systems, which is a product of two factors: (i) the randomized motion of the active particles, (ii) the ordered motion due to the alignment effects or initially ordered configuration.

Why is it important?

Realizations of active matter in biology are manifold and exist at different scales. Some of them are: active colloids, bacterial suspensions and cytoskeleton in living cells.


We believe that there is great opportunity for further development to gain fundamental insight into the behavior of the active colloids, in particular, into the interplay between ordered and disordered motion.
