Scaling determination of the nonlinear I-V characteristics for 2D superconducting networks
Petter Minnhagen, Beom Jun Kim, A. Gronlund
It is shown from computer simulations that the current-voltage (-) characteristics for the two-dimensional XY model with resistively-shunted Josephson junction dynamics and M…
Prisoners' dilemma in real-world acquaintance networks: Spikes and quasi-equilibria induced by the interplay between structure and dynamics
Petter Holme, Ala Trusina, Beom Jun Kim +1
We study Nowak and May's spatial prisoners' dilemma game driven by mutations (random choices of suboptimal strategies) on empirical social networks. The time evolution of the coope…
Quantum and classical diffusion in small-world networks
Beom Jun Kim, H. Hong, M. Y. Choi
We study numerically quantum diffusion of a particle on small-world networks by integrating the time-dependent Schrödinger equation with a localized initial state. The participatio…
Netons: Vibrations of Complex Networks
Beom Jun Kim, H. Hong, M. Y. Choi
We consider atoms interacting each other through the topological structure of a complex network and investigate lattice vibrations of the system, the quanta of which we call {\em n…
Direct Evidence of the Discontinuous Character of the Kosterlitz-Thouless Jump
Petter Minnhagen, Beom Jun Kim
It is numerically shown that the discontinuous character of the helicity modulus of the two-dimensional XY model at the Kosterlitz-Thouless (KT) transition can be directly related…
Optimal Size of a Complex Network
H. Hong, Beom Jun Kim, M. Y. Choi
We investigate the response behavior of an Ising system, driven by an oscillating field, on a small-world network, with particular attention to the effects of the system size. The…
