    "abstract": "The properties of the kaon, $K$, and antikaon, $\\kbar$, in nuclear medium are\nstudied in the quark-meson coupling (QMC) model. Employing a constituent\nquark-antiquark (MIT bag model) picture, their excitation energies in a nuclear\nmedium at zero momentum are calculated within mean field approximation. The\nscalar, and the vector mesons are assumed to couple directly to the nonstrange\nquarks and antiquarks in the $K$ and $\\kbar$ mesons. It is demonstrated that\nthe $\\rho$ meson induces different mean field potentials for each member of the\nisodoublets, $K$ and $\\kbar$, when they are embedded in asymmetric nuclear\nmatter. Furthermore, it is also shown that this $\\rho$ meson potential is\nrepulsive for the $K^-$ meson in matter with a neutron excess, and renders\n$K^-$ condensation less likely to occur.",
