An extension of the quantum mechanical central limit theorem provides a linear continuum model of the quantum fluctuations near a stable pumped state of a discrete atomic model such as the Dicke Hepp Lieb maser model. This procedure can be reversed to select an appropriate atomic model whose limit g

We consider the evolution of a classical Heisenberg ferromagnetic spin chain in its continuum limit in higher spatial dimensions. It is shown that the evolution of a radially symmetric chain could be identified with the motion of a helical space curve as in the linear case. The resulting invariant e

The classical equations of motion of a continuum Heisenberg spin system in N dimensions are written in the form of equations for a particle field and a gauge field. Known results, such as the exact solution for N = 1 and the self-dual solution for N = 2, are recovered. Of the new results we mention:
