Quantum de Sitter horizon entropy from quasicanonical bulk, edge, sphere and topological string partition functions

A bstract Motivated by the prospect of constraining microscopic models, we calculate exact one-loop corrected de Sitter entropy (the logarithm sphere partition function) for every effective field theory quantum gravity, with particles in arbitrary spin representations. In doing so, universally relate function to quotient a quasi-canonical bulk and Euclidean edge function, given integrals characters encoding spectrum observable universe. Expanding character splits (entanglement) into quasinormal mode (quasiqubit) contributions. For 3D higher-spin gravity formulated as an sl( n ) Chern-Simons theory, obtain all-loop results. Further this, show that has exponentially large landscape vacua absolute value squared topological string function. generic formalism succinctly relates dS, AdS ± conformal Holography is exhibited quasi-exact bulk-edge cancelation.
