摘要

We study the disk partition function of double-scaled SYK model (DSSYK) in the small λ limit, where λ = log q is the coupling of DSSYK. We find that the partition function receives non-perturbative corrections in λ, which can be resummed by the cubic power of the Dedekind eta function in a certain low temperature limit. We also discuss a possible bulk interpretation of our findings.
