- The Chromo-Weibel Instability Michael Strickland Física, Astronomía y Matemáticas Non Quark Gluon Plasma Thermalization Isotropization I discuss the physics of non-Abelian plasmas which are locally anisotropic in momentum space. Suchmomentum-space anisotropies are generated by the rapid longitudinal expansion of the matter created in the first1 fm/c of an ultrarelativistic heavy ion collision. In contrast to locally isotropic plasmas anisotropic plasmashave a spectrum of soft unstable modes which are characterized by exponential growth of transverse chromomagnetic/-electric fields at short times. This instability is the QCD analogue of the Weibel instability of QED.Parametrically the chromo-Weibel instability provides the fastest method for generation of soft backgroundfields and dominates the short-time dynamics of the system. The existence of the chromo-Weibel instabilityhas been proven using diagrammatic methods, transport theory, and numerical solution of classical Yang-Millsfields. I review the results obtained from each of these methods and discuss the numerical techniques which arebeing used to determine the late-time behavior of plasmas subject to a chromo-Weibel instability. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437521 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2C Vol.37
