de Sitter时空中拓扑缺陷引起的真空极化

Vacuum polarization by topological defects in de Sitter spacetime

E. R. Bezerra de Mello

摘要:

本文研究了具有引力拓扑亏损的de Sitter时空中的大质量量子标量场的真空极化效应。具体地,我们计算场平方的真空期望值$<Φ^2>$。由于这项研究是在纯de Sitter空间中进行的,因此我们主要对缺陷的存在所引起的效应感兴趣。

英文摘要:

In this paper we investigate the vacuum polarization effects associated with a massive quantum scalar field in de Sitter spacetime in the presence of gravitational topological defects. Specifically we calculate the vacuum expectation value of the field square, $<Φ^2>$. Because this investigation has been developed in a pure de Sitter space, here we are mainly interested on the effects induced by the presence of the defects.
