Second to first order phase transition; coevolutionary versus structural balance
M. Ghanbarzadeh Noudehi, A. Kargaran, N. Azimi-Tafreshi +1
In social networks, the balance theory has been studied by considering either the triple interactions between the links (structural balance) or the triple interaction of nodes and…
Emergence of oscillations in fixed energy sandpile models on complex networks
Davood Fazli, Nahid Azimi-Tafreshi
Fixed-energy sandpile (FES) models, introduced to understand the self-organized criticality, show a continuous phase transition between absorbing and active phases. In this work, w…
Spatial Asymmetric Two dimensional Continuous Abelian Sandpile Model
N. Azimi-Tafreshi, H. Dashti-Naserabadi, S. Moghimi-Araghi
We insert some asymmetries in the continuous Abelian sandpile models, such as directedness and ellipticity. We analyze probability distribution of different heights and also find t…
Continuous Abelian Sandpile Model in Two Dimensional Lattice
N. Azimi-Tafreshi, E. Lotfi, S. Moghimi-Araghi
We define a new version of sandpile model which is very similar to Abelian Sandpile Model (ASM), but the height variables are continuous ones. With the toppling rule we define in o…
