Abstract: The free energy distribution across the interface of coexisting quark and hadron mat-ter is studied in the framework of lattice QCD. We calculate the interface tension α with the “differential method” for pure SU(3) gauge theory and in the presence of dynamical quarks with four flavors. Using lattices with spatial volume82×16it turns out that α is very small and compatible with zero. The chiral condensate indicates the same width of the domain wall as the Polyakov loop distribution and the other thermodynamical observables.
