Abstract
The regulation of thermal transport in complex networks is a challenging topic. This paper focuse on thermal transport in the Erdős-Rényi network by adjusting two coefficients: the number of cycle structures and the cycle ratio. The results indicate that the increase of cycles in Erdős-Rényi networks leads to enhanced phonon localization and reduced efficiency in thermal transport. Further more, as the average cycle ratio increases, we observe an improvement of the network’s thermal transport efficiency, accompanied by thermal rectification phenomena. Finally, through the analysis of participation ratio, eigenvalue spectra, and node vibration time series, we clarified that the variations in phonon localization and the widths of the phonon spectrum are key factors influencing the thermal transport in complex networks. This work enables control of thermal transport by adjusting the structural characteristics of the network and provides further exploration and development of phonon localization in disordered systems.
