Reweighting method in finite density lattice QCD
  Finite density simulations require dynamical fermions which are computationally demanding. We employ Ferrenberg and Swendsen reweighting method to reduce the number of ensembles needed. We use their method to do a combined reweighting in both $\beta$ and quark number $k$ on an ensemble generated by the Kentucky group.
