Chiral waves in quark matter

Abstract

A mini-review of non-uniform phases in quark matter is presented, with particular attention to the pion condensation, also known as chiral density waves or chiral spirals. The phase diagram of strongly-interacting matter may involve such a phase, placed on the quarkyonic island between the baryonic phase and the chirally-restored quark-gluon plasma.Comment: 10 pages, 3 figures, presented at HIC for FAIR Workshop, XXVIII Max Born Symposium "Three days on Quarkyonic Island", Wroclaw, poland, 19-21 May 201
