The mechanistic origin of branching-driven nucleation in abrupt phase transitions
Leyang Xue, Shengling Gao, Bnaya Gross +5
Phase transitions are the macroscopic manifestation of microscopic processes that drive a system towards a new state. The detailed evolution of these processes, particularly in abr…
Iterative structural coarse-graining for contagion dynamics in complex networks
Leyang Xue, Zengru Di, An Zeng
Contagion dynamics in complex networks drive critical phenomena such as epidemic spread and information diffusion,but their analysis remains computationally prohibitive in large-sc…
Social contagion with emotional group interactions
YuQianqian Ma, Peng Zhang, Leyang Xue
Individual decisions and behaviors are shaped not only by direct interactions with others but also by the collective emotional dynamics within groups. In this work, we introduce th…
Nucleation phenomena and extreme vulnerability of spatial k-core systems
Leyang Xue, Shengling Gao, Lazaros K. Gallos +4
K-core percolation is a fundamental dynamical process in complex networks with applications that span numerous real-world systems. Earlier studies focus primarily on random network…
