Abstract

This paper analyzes the dressed-photon–phonon energy transfer from several nanometer-sized particles for an input signal terminal (NPI) to that for output signal terminals (NPO), which are arranged in rotationally symmetric and asymmetric manners. A quantum walk model is used for numerical calculations by assuming a pentagonal wheel arrangement. In the case where the number of connected spokes of the wheel is odd, the signal transfer route is a triply degenerate bright walk. In the case where is even, this route is decomposed into bright and dark walks. Since some input signals are injected into the dark walk and are confined in this walk, the output signal transfer rate is smaller than that in the case of the odd . The degeneracy in the bright walk and confinement in the dark walk are found also in other polygonal arrangements. It was demonstrated that their features are independent of the number of NPI on the rim of the wheel of these arrangements.
