Network connectivity has been thoroughly investigated in several domains, including physics, neuroscience, and social sciences. This work tackles the possibility of characterizing the topological properties of real-world networks from a quantum-inspired perspective. Starting from the normalized Laplacian of a network, we use a well-defined procedure, based on the dressing transformations, to derive a 1-dimensional Schrödinger-like equation characterized by the same eigenvalues. We investigate the shape and properties of the potential appearing in this equation in simulated small-world and scale-free network ensembles, using measures of fractality. Besides, we employ the proposed framework to compare real-world networks with the Erdős-Rényi, Watts-Strogatz and Barabási-Albert benchmark models. Reconstructed potentials allow to assess to which extent real-world networks approach these models, providing further insight on their formation mechanisms and connectivity properties.
网络连接性在物理、神经科学和社会科学等多个领域都得到了深入研究。本工作从量子启发的角度探讨了刻画真实世界网络拓扑性质的可能性。从网络的归一化拉普拉斯算子出发,我们使用基于修饰变换的明确定义的过程,推导出一个具有相同本征值的 1 维薛定谔型方程。我们使用分形测度来研究这个方程中出现的势的形状和性质,在模拟的小世界和无标度网络集合中进行研究。此外,我们还使用提出的框架将真实世界网络与 Erdős-Rényi、Watts-Strogatz 和 Barabási-Albert 基准模型进行比较。重建的势可以评估真实世界网络与这些模型的接近程度,从而进一步深入了解它们的形成机制和连接性质。
