Abstract

We identify a minisuperspace of complex deformations of ABJM theory for which the partition function specifies the amplitude of an eternally inflating universe. The boundary theory predicts that the bosonic bulk is effectively in the Hartle-Hawking no-boundary state, with a subleading ‘tunneling’ contribution. This holographic model of inflation also reveals a close connection between the swampland distance and cobordism conjectures, and the condition for the asymptotic wave function to predict classical behavior in geometry and fields.
