Ferromagnetic phase transition in Barabási-Albert networks
TL;DR: Ising spins put onto a Barabasi-Albert scale-free network show an effective phase transition from ferromagnetic to paramagnetism upon heating, with an effective critical temperature increasing as the logarithm of the system size as discussed by the authors.
Journal ArticleDOI
A simple model of bank bankruptcies
TL;DR: In this paper, a new model of directed percolation is introduced as a simple representation for contagion process and mass bankruptcies in banking systems and critical values of a mean density of interbank connections as well as static and dynamic scaling laws for the statistics of avalanche bankruptcies are found.
Journal ArticleDOI
Self-organized criticality in a model of collective bank bankruptcies
TL;DR: In this paper, a simple model of banking networks based on the random directed percolation was proposed to answer the question of whether phenomena of collective bankruptcies are related to self-organized criticality.
