Cluster-size heterogeneity in the two-dimensional Ising model
Woo Seong Jo, Su Do Yi, Seung Ki Baek +1
We numerically investigate the heterogeneity in cluster sizes in the two-dimensional Ising model and verify its scaling form recently proposed in the context of percolation problem…
Double resonance in the infinite-range quantum Ising model
Sung-Guk Han, Jaegon Um, Beom Jun Kim
We study quantum resonance behavior of the infinite-range kinetic Ising model at zero temperature. Numerical integration of the time-dependent Schrödinger equation in the presence…
Double stochastic resonance in the mean-field -state clock models
Seung Ki Baek, Beom Jun Kim
A magnetic system with a phase transition at temperature may exhibit double resonance peaks under a periodic external magnetic field because the time scale matches the extern…
Force correlations in molecular and stochastic dynamics
Su Do Yi, Beom Jun Kim
A molecular gas system in three dimensions is numerically studied by the energy conserving molecular dynamics (MD). The autocorrelation functions for the velocity and the force are…
Time Reversibility of Quantum Diffusion in Small-world Networks
Sung-Guk Han, Beom Jun Kim
We study the time-reversal dynamics of a tight-binding electron in the Watts-Strogatz (WS) small-world networks. The localized initial wave packet at time diffuses as time pr…
