摘要：
The behavior of a arbitrary coupled quantum scalar field is studied in the background of the Godel spacetime. Closed forms are derived for the effective action and the vacuum expectation value of quadratic field fluctuations by using zeta-function regularization. Based on these results, we argue that causality violation presented in this spacetime cannot be removed by quantum effects.
