Lattice Correlation Functions from Differential Equations
Federico Gasparotto, Andreas Rapakoulias, Stefan Weinzierl +1
We discuss how methods developed in the context of perturbation theory can be applied to the computation of lattice correlation functions, in particular in the non perturbative reg…

Real time lattice correlation functions from differential equations
Federico Gasparotto, Stefan Weinzierl, Xiaofeng Xu
We report on an exact calculation of lattice correlation functions on a finite four-dimensional lattice with either Euclidean or Minkowskian signature. The lattice correlation func…
