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…
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…
Voter model on a directed network: Role of bidirectional opinion exchanges
Sung-Guk Han, Jaegon Um, Beom Jun Kim
The voter model with the node update rule is numerically investigated on a directed network. We start from a directed hierarchical tree, and split and rewire each incoming arc at t…
Reentrant phase transition in a predator-prey model
Sung-Guk Han, Su-Chan Park, Beom Jun Kim
We numerically investigate the six-species predator-prey game in complex networks as well as in -dimensional hypercubic lattices with . The interaction topology of…
