Hartle-Hawking wavefunction in double scaled SYK

High Energy Physics - Theory 2023-04-05 v3

Abstract

We compute the transition amplitude between the chord number 00 and \ell states in the double scaled SYK model and interpret it as a Hartle-Hawking wavefunction of the bulk gravitational theory. We observe that the so-called un-crossed matter correlators of double scaled SYK model are obtained by gluing the Hartle-Hawking wavefunctions with an appropriate weight.
