Strongly Coupled Plasmas and Gauge/String Duality

摘要: Strongly Coupled Plasmas and Gauge/String Duality Page 1 Strongly Coupled Plasmas and Gauge/String Duality Laurence Yaffe University of Washington UVa/UKy Colloquia, April 2007 – p. 1/28 Page 2 Outline 1. Heavy ion collisions and quark gluon plasma (QGP) 2. Strongly coupled versus weakly coupled systems 3. Theoretical techniques 4. Gauge/string duality 5. Applications to strongly coupled non-Abelian plasmas 6.
