Physics and Astronomy Colloquium: Most vortical fluid - globally polarized Quark-Gluon Plasma
Speaker: Prof. Sergei Voloshin, Wayne State University
Title: Most vortical fluid — globally polarized Quark-Gluon Plasma
Abstract: 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.
Physics and Astronomy Colloquia are presented Thursdays, at 3:45 pm, in Room 245 of the Physics Building, unless otherwise noted. Refreshments are served at 3:30 pm. Please check the following website for this week's speaker and topic:
