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…
Two-dimensional melting in simple atomic systems: continuous vs. discontinous melting
Sang Il Lee, Sung Jong Lee
We investigate the characteristics of two dimensional melting in simple atomic systems via isobaric-isothermal () and isochoric-isothermal () molecular dynamics simulatio…
Coarsening Dynamics of an Antiferromagnetic XY model on the Kagome Lattice: Breakdown of the Critical Dynamic Scaling
Sangwoong Park, Bongsoo Kim, Sung Jong Lee
We find a breakdown of the critical dynamic scaling in the coarsening dynamics of an antiferromagnetic {\em XY} model on the kagome lattice when the system is quenched from disorde…
Patterns of Striped order in the Classical Lattice Coulomb Gas
Sung Jong Lee, Jong-Rim Lee, Bongsoo Kim
We obtain via Monte Carlo simulations the low temperature charge configurations in the lattice Coulomb gas on square lattices for charge filling ratio in the range $1/3 < f < 1…
