Coarsening of two dimensional XY model with Hamiltonian dynamics: Logarithmically divergent vortex mobility
Keekwon Nam, Woon-Bo Baek, Bongsoo Kim +1
We investigate the coarsening kinetics of an XY model defined on a square lattice when the underlying dynamics is governed by energy-conserving Hamiltonian equation of motion. We f…
Double transitions, non-Ising criticality and critical absorbing phase in an interacting monomer-dimer model on a square lattice:
Keekwon Nam, Sangwoong Park, Bongsoo Kim +1
We present a numerical study on an interacting monomer-dimer model with nearest neighbor repulsion on a square lattice, which possesses two symmetric absorbing states. The model is…
Coarsening Kinetics of a Two Dimensional O(2) Ginzburg-Landau Model: Effect of Reversible Mode Coupling
Keekwon Nam, Bongsoo Kim, Sung Jong Lee
We investigate, via numerical simulations, the phase ordering kinetics of a two- dimensional soft-spin O(2) Ginzburg-Landau model when a reversible mode cou- pling is included via…
Nonequilibrium critical relaxations of the order parameter and energy in the two-dimensional ferromagnetic Potts model
Keekwon Nam, Bongsoo Kim, Sung Jong Lee
The static and dynamic critical properties of the ferromagnetic q-state Potts models on a square lattice with q = 2 and 3 are numerically studied via the nonequilibrium relaxation…
