    "abstract": "We study bipartite entanglement in a general one-particle state, and find\nthat the linear entropy, quantifying the bipartite entanglement, is directly\nconnected to the paricitpation ratio, charaterizing the state localization. The\nmore extended the state is, the more entangled the state. We apply the general\nformalism to investigate ground-state and dynamical properties of entanglement\nin the one-dimensional Harper model.",
