Yang-Mills Magneto-Fluid Unification
We generalize the hybrid magneto-fluid model of a charged fluid interacting
with an electromagnetic field to the dynamics of a relativistic hot fluid
interacting with a non-Abelian field. The fluid itself is endowed with a
non-Abelian charge and the consequences of this generalization are worked out.
Applications of this formalism to the Quark Gluon Plasma are suggested.Comment: 6 pages, RevTex
Isospin Squeezed States, Disoriented Chiral condensates and Pion Production: A Dynamic Group Theoretical Approach
We make a complete dynamical study of Isotopic spin conservation effects on
the multiplicity distributions of both hard and soft pions emitted in a quark
gluon plasma undergoing a non-equilibrium phase transition.Comment: 21 pages, 9 figures, RevTeX4 macr
Order-chaos transitions in field theories with topological terms: a dynamical systems approach
We present a comparative study of the dynamical behaviour of topological
systems of recent interest, namely the non-Abelian Chern-Simons Higgs system
and the Yang-Mills Chern-Simons Higgs system. By reducing the full field
theories to temporal differential systems using the assumption of spatially
homogeneous fields , we study the Lyapunov exponents for two types of initial
conditions. We also examine in minute detail the behaviour of the Lyapunov
spectra as a function of the various coupling parameters in the system. We
compare and contrast our results with those for Abelian Higgs, Yang-Mills Higgs
and Yang-Mills Chern-Simons systems which have been discussed by other authors
recently. The role of the various terms in the Hamiltonians for such systems in
determining the order-disorder transitions is emphasized and shown to be
counter-intuitive in the Yang-Mills Chern-Simons Higgs systems.Comment: 19 pages,15 figures available in hard copy from C. Mukku, and through
