Description
Active matter is a new kind of soft matter relevant to describe numerous biological problems with manifold realizations in two dimensions. I will discuss several intriguing aspects of its phase behavior including the melting of an active solide (with special emphasis on the role of dislocations and disclinations) and the mechanisms leading to motility induced phase separation.
