    An exact solution for a nonrotating boson star in (2+1) dimensional gravity with a negative cosmological constant is found. The relations among mass, particle number, and radius of the (2+1) dimensional boson star are shown.Comment: 16 pages, 7 figures, needs REVTeX (2nd revised version

    Deconstructing Scalar QED at Zero and Finite Temperature

    Full text link
    We calculate the effective potential for the WLPNGB in a world with a circular latticized extra dimension. The mass of the WLPNGB is calculated from the one-loop quantum effect of scalar fields at zero and finite temperature. We show that a series expansion by the modified Bessel functions is useful to calculate the one-loop effective potentials.Comment: 12 pages, 2 figures. RevTeX

    Shape of Deconstruction

    Full text link
    We construct a six-dimensional Maxwell theory using a latticized extra space, the continuum limit of which is a shifted torus recently discussed by Dienes. This toy model exhibits the correspondence between continuum theory and discrete theory, and give a geometrical insight to theory-space model building.Comment: 10 pages, 2 figures, RevTeX4. a citation adde

    Quantum Scattering in Two Black Hole Moduli Space

    Full text link
    We discuss the quantum scattering process in the moduli space consisting of two maximally charged dilaton black holes. The black hole moduli space geometry has different structures for arbitrary dimensions and various values of dilaton coupling. We study the quantum effects of the different moduli space geometries with scattering process. Then, it is found that there is a resonance state on certain moduli spaces.Comment: 15 pages, 19 figures, RevTeX 3.

    電氣泳動による濾紙上アミノ酸の分離について(第1報)

    Get PDF
    溶媒によつて展開を行う通常のペーパークロマトグラフィーについては最近盛に改良法が発表せられてゐるが、通電クロマトグラフィーについてはWieland及びFisherが数種類の純粹アミノ酸混合物の分離に用いてゐる他、現在入手し得る文献ではJ.Am.Chem.Socに一二の報告が見える程度である。著者は濾紙に緩衝溶液を滲透させて電流を通じ、濾紙中央部に滴下した溶液中のアミノ酸を種々の等電点の差を利用して分離を試みた結果、数種の純粹アミノ酸混合物を互いに分離し更に蛋白質加水分解物より所謂ヘキソンベースであるアルギニン、リジン、ヒスチヂンを分離することが出来たので報告する
