Langevin dynamics of generalized spins as SU( $N$ ) coherent states

David Dahlbom, Cole Miles, Hao Zhang +2

Classical models of spin systems traditionally retain only the dipole moments, but a quantum spin state will frequently have additional structure. Spins of magnitude $S$ have $N=2S…

Understanding temperature-dependent SU( $3$ ) spin dynamics in the $S = 1$ antiferromagnet Ba $_{2}$ FeSi $_{2}$ O $_{7}$

Seung-Hwan Do, Hao Zhang, David A. Dahlbom +9

Quantum magnets admit more than one classical limit and $N$ -level systems with strong single-ion anisotropy are expected to be described by a classical approximation based on SU($N…

Geometric integration of classical spin dynamics via a mean-field Schrödinger equation

David Dahlbom, Hao Zhang, Cole Miles +3

The Landau-Lifshitz equation describes the time-evolution of magnetic dipoles, and can be derived by taking the classical limit of a quantum mechanical spin Hamiltonian. To take th…
