摘要：
In the framework of a perturbative approach we evaluate the vacuum polarization of a massless electromagnetic field in the spacetime of multiple cosmic strings. We show that in addition to the energy density arising from vacuum fluctuations around each of the strings individually, there also exists an additional effect of vacuum polarization, which results in the Casimir force between two parallel cosmic strings.
