| Abstract: | The Casimir energy for massless scalar field which satisfies periodic boundary conditions in two-dimensional domain wall background is calculated by making use of general properties of renormalized stress-tensor. The line element of domain wall is time dependent, the trace anomaly which is the nonvanishing T
for a conformally invariant field after renormalization, represent the back reaction of the dynamical Casimir effect. |
