Description
Ultrarelativistic nuclear collisions provide unique possibility to
study the matter at extreme conditions not available in any other
laboratory settings. These include highest temperature and energy
density, strongest electro-magnetic fields, lowest viscosity over
entropy density (ideal liquid) and, what is the main theme of this
presentation, the highest vorticity, originating in the large angular
momentum of the system. I will present the recent developments in
understanding of the role of vorticity in high energy nuclear
collision dynamics, as well as latest experimental measurements of the
global polarizations - the particle spin alignment with the system
orbital momentum. The relation of the global polarization effect to
Barnett and Einstein-de Haas effects, as well as to chiral anomalous
effects, both in nuclear collisions and condensed matter, will be also
briefly discussed.
