摘要
从具有自相互作用的Higgs标量场在温度背景下的有效拉氏量出发,推广量子规范场论的能动张量为4维协变形式,求解了温度效应修正后的整体磁单极核外的引力场方程,得到了近似解.与零温条件下的结果比较,其度规有一附加的温度项.讨论了引力场中光线(或引力波)的传播问题以及其在宇宙演化期间的效应.
Proceeding from the effective Lagrangian of the Higgs scalar field with selfinteraction considering temperature effect, extended energymomentum tensor in quantum gauge field theory into 4dimension covariant form, solved the gravitational field equation outside the core of global monopole at the background of temperature, obtained an approximative solution. Comparing with the result under condition of zero temperature, the metric acquired modification which had an additional term ralated to temperature. Discussed the propagation of light (or gravitational wave) in the gravitational field of global monopole and its effect during the period of the universe evolution.
