Creep motion of a domain wall in the two-dimensional random-field Ising model with a driving field
R. H. Dong, B. Zheng, N. J. Zhou
With Monte Carlo simulations, we study the creep motion of a domain wall in the two-dimensional random-field Ising model with a driving field. We observe the nonlinear fieldvelocit…

Hamiltonian equation of motion and depinning phase transition in two-dimensional magnets
R. H. Dong, B. Zheng, N. J. Zhou
Based on the Hamiltonian equation of motion of the theory with quenched disorder, we investigate the depinning phase transition of the domain-wall motion in two-dimensional m…

Critical domain-wall dynamics of model B
R. H. Dong, B. Zheng, N. J. Zhou
With Monte Carlo methods, we simulate the critical domain-wall dynamics of model B, taking the two-dimensional Ising model as an example. In the macroscopic short-time regime, a dy…
