    The Gravitational Field of a Charged Global Monopole

    • 摘要: 给出了弯曲空间中整体带电单极子的运动方程,能量-动量张量及度规表达式。其引力效应等价于立体亏损角加上原点处质量。证明了这个质量依赖于电荷,光电荷Q小于临界值Qer时,质量为负,呈现排斥力场,而当Q大于Qcr时,质量为正,呈现吸引力场。

       

      Abstract: This paper presents the equations of motion,the energy-momentum tensor and the metric for a charged global monopole in the curved space,A charged global monopole formed as a consequence of the spontaneous breakdown of a global symmetry should have a mass that grows linearly with the distance off its core, The gravitational effect of th is configuration is equivalent to that of deficit solid angle in the metric and relatively tiny mass at the origen.It is shown that this small effective mass depends on the charge.There exist negative mass and repellency when the charge number Q is less than a critical value Q_(cr),and there will be positive mass and attractive field when Q is larger than Q_(cr).
