ColemanWeinberg symmetry breaking in a rotating spacetime
Abstract
The effective potential of a massless scalar field in a Goedel spacetime is analyzed as a model for investigating the symmetry breaking processes usually leading to inflationary cosmologies in the presence of a primordial cosmological rotation. The partially summed JackParker expression for the DeWittSchwinger expansion of the effective action is used, and it is found that symmetry is restored by rotation if the curvature coupling constant is negative and broken if positive, this result being independent of the value of the rotation.
