Thermodynamics of QCD at large quark chemical potential

Andreas Gerhold, Andreas Ipp, Anton Rebhan

We review the existing weak-coupling results on the thermodynamic potential of deconfined QCD at small and large quark chemical potential and compare with results from lattice gaug…

Nonperturbative renormalization of Phi-derivable approximations in theories with fermions

U. Reinosa

We show how to renormalize Phi-derivable approximations in a theory with a fermionic field coupled to a self-interacting scalar field through a Yukawa interaction. The nonperturbat…

Hard-loop dynamics of non-abelian plasma instabilities

Michael Strickland

I discuss recent advances in the understanding of non-equilibrium gauge field dynamics in plasmas which have particle distributions which are locally anisotropic in momentum space.…

Asymptotic thermal quark masses and the entropy of QCD in the large-N_f limit

Jean-Paul Blaizot, Andreas Ipp, Anton Rebhan +1

We study the thermodynamics of QCD in the limit of large flavor number (N_f) and test the proposal to resum the physics of hard thermal loops (HTL) through a nonperturbative expres…

Study of the gluon propagator in the large-N_f limit at finite temperature and chemical potential for weak and strong couplings

Jean-Paul Blaizot, Andreas Ipp, Anton Rebhan

At finite temperature and chemical potential, the leading-order (hard-thermal-loop) contributions to the gauge-boson propagator lead to momentum-dependent thermal masses for propag…

Dynamics of Quark-Gluon-Plasma Instabilities in Discretized Hard-Loop Approximation

Anton Rebhan, Paul Romatschke, Michael Strickland

Non-Abelian plasma instabilities have been proposed as a possible explanation for fast isotropization of the quark-gluon plasma produced in relativistic heavy-ion collisions. We st…
