# Hartle-Hawking wavefunction in double scaled SYK

Dec 2022

We compute the transition amplitude between the chord number $0$ and $\ell$states in the double scaled SYK model and interpret it as a Hartle-Hawkingwavefunction of the bulk gravitational theory. We observe that the so-calledun-crossed matter correlators of double scaled SYK model are obtained by gluingthe Hartle-Hawking wavefunctions with an appropriate weight.
