Sphere and disk partition functions in Liouville and in matrix integrals
Raghu Mahajan, Douglas Stanford, Cynthia Yan
We compute the sphere and disk partition functions in semiclassical Liouville and analogous quantities in double-scaled matrix integrals. The quantity sphere/disk^2 is unambiguous…
Subleading Weingartens
Douglas Stanford, Zhenbin Yang, Shunyu Yao
Haar integrals over the unitary group contain subleading terms that are needed for unitarity. We study analogous effects in the time evolution operators of JT gravity and Brownian…
Wormholes without averaging
Phil Saad, Stephen H. Shenker, Douglas Stanford +1
After averaging over fermion couplings, SYK has a collective field description that sometimes has "wormhole" solutions. We study the fate of these wormholes when the couplings are…
