Exact Evaluation of Lattice-Regularized Scalar Field Vacuum Amplitude via Site Permutations
Year: 2026
Type: preprint
Abstract: A novel approach to a computation of vacuum amplitude for a single scalar field in any number of dimensions with arbitrary potential on a lattice is proposed. The computation involves symmetrization of kinetic exponential factor in the path integral over all permutations of lattice sites and Waring decomposition of the symmetrized expression.
