A Boolean-Lattice Perspective for All-Loop Two-Site Cosmological Wavefunction
Yanfeng Hang, Cong Shen
We revisit the shifted-tree decomposition formula proposed in our previous work arXiv:2410.17192 for two-site cosmological wavefunction coefficients. For the two-site bubble-like f…

A Note on Kinematic Flow and Differential Equations for Two-Site One-Loop Graph in FRW Spacetime
Yanfeng Hang, Cong Shen
In this work, we systematically study the differential systems governing loop-level wavefunction coefficients of conformally-coupled scalar field theory within a general power-law…
