Map from one-dimensional quantum field theory to quantum chaos on a two-dimensional torus.
Dynamics of a class of quantum field models on a one-dimensional (1D) lattice in a Heisenberg picture is mapped onto a class of quantum chaotic one-body systems on a configurational 2D torus (or 2D lattice) in the Schrödinger picture. The continuum field limit of the former corresponds to the quasiclassical limit of the latter.
