Grand Canonical Potential for a Static Quark-Antiquark Pair at finite   chemical potential
  The grand canonical potential for a static quark-antiquark pair at non-vanishing chemical potential was determined at several temperatures. The dynamical staggered simulations were carried out with 2+1 physical quarks along the Lines of Constant Physiscs (LCP).
