Relaxation dynamics of a system with a grain boundary
Recently an interesting phase transition scenario in the context of a planar Ising system with a grain boundary was revealed [Abraham et al., Phys. Rev. Lett. 93, 076101 (2004)].

| Čoahkkáigeassu: | Recently an interesting phase transition scenario in the context of a planar Ising system with a grain boundary was revealed [Abraham et al., 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. |
