We study the temperature and chemical potential dependence of the momentum distributions of quasi-particles in the quark-gluon plasma. The Wigner functions of quarks and gluons, whose spatial integration is related to the momentum distributions, are calculated with the 2-flavor lattice QCD simulations. We found significant changes of the shape of the momentum distribution around the boundary between the hadronic phase and the quark-gluon plasma. This provides a new tool to study the behavior of the quasi-particles in the strongly coupled QGP.
