Spin Dynamics of an Ising-like , = 1/2 Antiferromagnet on Finite Chains and Triangular LatticesWe propose a method of studying dynamics of an Ising-like model, and apply it to an antiferromagnetic model on a linear chain and on a triangular lattice. In the former, dynamics of solitons are discussed and, in the latter, stability of a three sublattice spin structure occurring in the classical case is examined.

Tom Wellswever, treatments of generally interconnected and interacting topological defects present formidable problems of cooperative dynamics in complex physical systems. In this talk we take up two concrete examples studied recently in our research group.

Tom Wellse equilibrium properties of such systems exhibit scaling that is now understood. Similarly, much progress has been made in our understanding of nucleation and spinodal decomposition when the system is quenched below its critical point.. In this paper we are concerned with a different type of experim

Tom Wellslattice for the isotropic Heisenberg and planar ferromagnetic Hamiltonian with nearest neighbor interaction. We have obtained dynamical signatures of the Kosterlitz-Thouless transition in the XY model case . More recently, we have also discussed the vortex signatures in dynamic structure facto

Tom Wells.=-0.033 ~ -0.13K). The Ni. ions along the c-axis have the antiferromagnetic intrachain interaction (J/k.=16.6K) and the chains form the triangular lattice in the c-plane with a weak antiferromagnetic interchain interaction (J′/k.=0.28K). As early as in 1972, CLARK and MOULTON observed two magne
