Spin glass behavior of the antiferromagnetic Ising model on a scale-free network
M. Bartolozzi, T. Surungan, D. B. Leinweber +1
Antiferromagnetic Ising spins on the scale-free Barabasi-Albert network are studied via the Monte Carlo method. Using the replica exchange algorithm, we calculate the temperature d…
Scale-free networks in complex systems
M. Bartolozzi, D. B. Leinweber, T. Surungan +2
In the past few years, several studies have explored the topology of interactions in different complex systems. Areas of investigation span from biology to engineering, physics and…
Stochastic Opinion Formation in Scale-Free Networks
M. Bartolozzi, B. Leinweber, A. W. Thomas
The dynamics of opinion formation in large groups of people is a complex non-linear phenomenon whose investigation is just at the beginning. Both collective behaviour and personal…
Influence of Local Interactions in the Bak-Sneppen Model and Economic Applications
M. Bartolozzi, D. B. Leinweber, A. W. Thomas
In the present work we extend the Bak-Sneppen model for biological evolution by introducing local interactions between species. This ``environmental'' perturbation can modify the i…
Self-Similar Log-Periodic Structures in Western Stock Markets from 2000
M. Bartolozzi, S. Drozdz, D. B. Leinweber +2
The presence of log-periodic structures before and after stock market crashes is considered to be an imprint of an intrinsic discrete scale invariance (DSI) in this complex system.…
