Abstract
Abstract
This chapter focuses on the description of the phases of matter in two dimensions. Firstly, we briefly discuss the phase diagrams of bidimensional interacting passive systems. This short and schematic presentation is complemented with a rather complete bibliography that should guide the readers in their study of this very rich subject. Secondly, we summarise very recent results on the phase diagrams of active Brownian disks and active dumbbell systems in two dimensions. The idea is to identify all the phases and to relate, when this is possible, the ones found in the passive limit with the ones observed at large values of the activity, at high and low densities, and for both types of constituents. Proposals for the mechanisms leading to these phases will be discussed. The physics of bidimensional active systems open many questions, some of which will be listed by the end of the Chapter.
