Non-Abelian plasma instabilities: SU(3) vs. SU(2)
Andreas Ipp, Anton Rebhan, Michael Strickland
We present the first 3+1 dimensional simulations of non-Abelian plasma instabilities in gauge-covariant Boltzmann-Vlasov equations for the QCD gauge group SU(3) as well as for SU(4…
Perturbative and Nonperturbative Kolmogorov Turbulence in a Gluon Plasma
M. E. Carrington, A. Rebhan
In numerical simulations of nonabelian plasma instabilities in the hard-loop approximation, a turbulent spectrum has been observed that is characterized by a phase-space density of…
Ginzburg-Landau phase diagram for dense matter with axial anomaly, strange quark mass, and meson condensation
Andreas Schmitt, Stephan Stetina, Motoi Tachibana
We discuss the phase structure of dense matter, in particular the nature of the transition between hadronic and quark matter. Calculations within a Ginzburg-Landau approach show th…
Calculation of the pressure of a hot scalar theory within the Non-Perturbative Renormalization Group
Jean-Paul Blaizot, Andreas Ipp, Nicolás Wschebor
We apply to the calculation of the pressure of a hot scalar field theory a method that has been recently developed to solve the Non-Perturbative Renormalization Group. This method…
Cold Quark Matter
Aleksi Kurkela, Paul Romatschke, Aleksi Vuorinen
We perform an O(alpha_s^2) perturbative calculation of the equation of state of cold but dense QCD matter with two massless and one massive quark flavor, finding that perturbation…
