Time-Dependent Behavior of the Spin-½ Anisotropic Heisenberg Model in Infinite Lattice Dimensions

M. Howard Lee, I. M. Kim, Raf Dekeyser

The spin van der Waals model may be regarded as an infinite-lattice-dimensional limit of the spin-\textonehalf{} anisotropic Heisenberg model. By solution of the generalized Langevin equation, time-dependent behavior is obtained. The geometry of realized Hilbert spaces lends a simple interpretation for critical dynamics.
