# Wilson spool The Wilson spool is a proposal to incorporate matter into the gravitational path integral in AdS3 or dS3. At the $G_N\to0$ limit, it reproduces the one-loop exact scalar field partition function on fixed backgrounds. ## Refs - original - [[2023#Castro, Coman, Fliss, Zukowski (Mar)]] (dS) - [[2023#Castro, Coman, Fliss, Zukowski (Apr, Letter)]] (dS and AdS) - extensions - [[2024#Bourne, Castro, Fliss]]: with spins, robust derivation, relation to QNM - [[2025#Fliss]]: JT with matter, dimensional reduction from 3D - [[2024#He]]: [[0170 TTbar|TTbar]] deformation in AdS3 - [[2025#Haupfear, Martin, Svesko, Zukowski]]: relation to Selberg zeta function - [[2025#Bourne, Fliss, Knighton]]: any hyperbolic 3d manifold
