We discuss the dynamics in finite density medium including a heavy impurityparticle (hadron or quark) with a heavy flavor, charm and bottom, at zerotemperature. As a system, we consider a $\bar{D}$ ($B$) meson embedded innuclear matter as a heavy impurity boson with SU(2) isospin symmetry. Asanother system, we also consider a charm (bottom) quark embedded in quarkmatter as a heavy impurity fermion with SU(3) color symmetry. We suppose avector current interaction with SU($n$) symmetry ($n \ge 2$) for the fermioncomposing the Fermi surface and the embedded heavy impurity particle, andcalculate the scattering amplitude perturbatively for the small couplingconstant up to one-loop level. We obtain that the scattering amplitude has alogarithmic enhancement in the large mass limit of the heavy impurity particle,and show that the perturbative calculation breaks down for any small couplingconstant in this limit.
