In preparation of lattice studies of the two-color QCD phase diagram we study\nchiral restoration and deconfinement at finite temperature with two flavors of\nstaggered quarks using an RHMC algorithm on GPUs. We first study unquenching\neffects in local Polyakov loop distributions, and the Polyakov loop potential\nobtained via Legendre transformation, in a fixed-scale approach for heavier\nquarks. We also present the chiral condensate and the corresponding\nsusceptibility over the lattice coupling across the chiral transition for\nlighter quarks. Using Ferrenberg-Swendsen reweighting we extract the maxima of\nthe chiral susceptibility in order to determine pseudo-critical couplings on\nvarious lattices suitable for chiral extrapolations. These are then used to fix\nthe relation between coupling and temperature in the chiral limit.\n
