Nonminimally coupled complex scalar field in classical and quantum cosmology
Abstract
We investigate a cosmological model with a complex scalar selfinteracting inflaton field nonminimally coupled to gravity. The different geometries of the Euclidean classically forbidden regions are represented. The instanton solutions of the corresponding Euclidean equations of motion are found by numerical calculations. These solutions give rather nontrivial examples of real tunnelling geometries. Possible interpretation of obtained results and their connection with inflationary cosmology is discussed.
