Abstract

The spin evolution equation of a classical inhomogeneous Heisenberg chain is derived and its exact equivalence (in the continuum limit) to a generalized nonlinear Schrödinger equation with x-dependent coefficients is proved. An extension of the AKNS-ZS formalism is given which enables us to solve the latter equation exactly for certain specific inhomogeneities. Energy-momentum transport along the chain is related to the solution of this equation.
