Abstract
This paper aims to formulate a field theory for the solution of classical N-body problem. In this paper, multi-length and time scale material behaviour is addressed from the viewpoint of lattice dynamics. A multiscale field theory that can work as an alternative to molecular dynamics simulation in studying statistical and finite temperature properties of materials is proposed. Atomistic definitions and the corresponding field representations of fundamental physical quantities are obtained. Time evolutions of conserved physical quantities are derived in terms of atomic variables and are expressed in terms of field quantities. The mathematical representation of conservation laws for a multiscale field theory is formulated.
