Quark diffusion coefficients in the phase structure of QCD — •Jonas Wessely¹, Jan M Pawlowski^1,2, and Nicolas Wink³ — ¹Institut für Theoretische Physik, Universität Heidelberg, Philosophenweg 16, 69120 Heidelberg, Germany — ²ExtreMe Matter Institute EMMI, GSI, Planckstr. 1, 64291 Darmstadt, Germany — ³Institut für Kernphysik, Technisch Universität Darmstadt, Schloessgartenstraße 2, 64289 Darmstadt, Germany

I present result on the quark diffusion coefficient for different (light) flavours at finite temperature and density. The diffusion coefficients are obtained via the Kubo relation from non-perturbative realtime diagrams which depend on single particle spectral functions of quarks and gluons. The latter are computed with a combination of spectral reconstructions and recently developed spectral functional techniques for the quark propagator spectral functions at finite T and µ_B.
