Zero-temperature relaxation of three-dimensional Ising ferromagnets
Zero-temperature relaxation of three-dimensional Ising ferromagnets
We investigate the properties of the Ising-Glauber model on a periodic cubic lattice of linear dimension $L$ after a quench to zero temperature. The resulting evolution is extremely slow, with long periods of wandering on constant energy plateaus, punctuated by occasional energy-decreasing spin-flip events. The characteristic time scale $\ensuremath{\tau}$ for …
