In the presented work we study, by means of numerical simulations, the
behaviour of a suspension of active ring polymers in the bulk and under lateral
confinement. When changing the separation between the confining planes and the
polymers' density, we detect the emergence of a self-organised dynamical state,
characterised by the coexistence of slowly diffusing clusters of rotating disks
and faster rings moving in between them. This system represents a peculiar case
at the crossing point between polymer, liquid crystals and active matter
physics, where the interplay between activity, topology and confinement leads
to a spontaneous segregation of a one component solution.Comment: 26 pages (single column), 10 figure
