Open inflation from quantum cosmology with a strong non-minimal coupling
Nuclear Physics B
We propose the mechanism of quantum creation of the open Universe in the observable range of values of Ω. This mechanism is based on the no-boundary quantum state with the Hawking-Turok instanton applied to the model with a strong nonminimal coupling of the inflaton field. We develop the slow roll perturbation expansion for the instanton solution and obtain a nontrivial contribution to the classical instanton action. The interplay of this classical contribution with the loop effects due todoi:10.1016/s0550-3213(99)00472-1 fatcat:ga42ao5sr5eodb6ylxra3guzm4
