Abstract:
Recently an interesting phase transition scenario in the context of a planar Ising system with a grain boundary was revealed [Phys. Rev. Lett. 93, 076101 (2004)]]. In this paper we study in more detail the relaxation dynamics of this system and show how the grain boundary acts as a guide spatially confining matter transport. This is done by performing simulations using the continuous time Monte Carlo algorithm with Kawasaki dynamics. We also set up the problem as a solid-on-solid model and formulate corresponding Langevin equations for the dynamics in two cases, with and without matter conservation.

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
