摘要

Vacuum-to-vacuum instantonic transitions modify the power spectrum of primordial gravitational waves. We evaluate the new form of the power spectrum for ordinary gravity as well as the parity violation induced in the spectrum by a modification of general relativity known as the Holst term and we outline the possible experimental consequences.
