    "abstract": "We study the properties of the $\\Theta^+$ in nuclear matter and $\\Theta^+$\nhypernuclei within the quark mean-field (QMF) model, which has been\nsuccessfully used for the description of ordinary nuclei and $\\Lambda$\nhypernuclei. With the assumption that the non-strange mesons couple only to the\n$u$ and $d$ quarks inside baryons, a sizable attractive potential of the\n$\\Theta^+$ in nuclear matter is achieved as a consequence of the cancellation\nbetween the attractive scalar potential and the repulsive vector potential. We\ninvestigate the $\\Theta^+$ single-particle energies in light, medium, and heavy\nnuclei. More bound states are obtained in $\\Theta^+$ hypernuclei in comparison\nwith those in $\\Lambda$ hypernuclei.",
