Currently, community detection in complex networks has become a hot-button topic. In this paper, based on the Spectral Clustering (SC) algorithm, we introduce the idea of Jacobi iteration, and then propose a novel algorithm J-SC for community detection in complex networks. Furthermore, the accuracy and efficiency of this algorithm are tested by some representative real-world networks and several computer-generated...
An eigen-equation of plasmon excitation in confined quasi-one-dimensional systems is presented. Besides dipole plasmons, quadrupole plasmons are found in the systems by comparing the eigen-solutions with the dipole response. For both dipole and quadrupole plasmons, the plasmon frequencies decrease with the increase of the system's length, and their size dependence can be well fitted by the plasmon...
