Classical Mechanics of a Three Spin Cluster
Paul A. Houle, Christopher L. Henley
A cluster of three spins coupled by single-axis anisotropic exchange exhibits classical behaviors ranging from regular motion at low and high energies, to chaotic motion at interme…

Semiclassical mechanics of a non-integrable spin cluster
P. A. Houle, N. G. Zhang, C. L. Henley
We study detailed classical-quantum correspondence for a cluster system of three spins with single-axis anisotropic exchange coupling. With autoregressive spectral estimation, we f…
