Impact of Higher-Order Interactions on Collective Motion
Maryam Masoumi, Amir Kargaran, Reza Jafari
Collective motion in self-propelled particle systems has been widely studied using the Vicsek model, which relies on pairwise alignment interactions. We introduce a generalized Vic…
Predicting success of cooperators across arbitrary heterogeneous environmental landscapes
Amir Kargaran, Kamran Kaveh, Krishnendu Chatterjee
Cooperation is central to the organization of complex biological and social systems. Most theoretical models assume homogeneous environments; in reality, populations inhabit spatia…
Hierarchical Balance Theory: Emergence of Instability in Follower Layer Below Critical Temperatures
Amir Kargaran, Houman Jafari, G. Reza Jafari
Hierarchy significantly shapes interactions in social structures by organizing individuals or groups based on status, power, or privilege. This study investigates how hierarchy aff…
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…
Response of the competitive balance model to the external field
Farideh Oloomi, Amir Kargaran, Ali Hosseiny +1
The competitive balance model was proposed as an extension of the structural balance theory, aiming to account for heterogeneities observed in real-world networks. In this model, d…
The structure of gene-gene networks beyond pairwise interactions
Nastaran Allahyari, Amir Kargaran, Ali Hosseiny +1
Despite its high and direct impact on nearly all biological processes, the underlying structure of gene-gene interaction networks is investigated so far according to pair connectio…
Hybrid balance theory: Heider balance under higher order interactions
M. H. Hakimi Siboni, A. Kargaran, G. R. Jafari
Heider's Balance Theory in signed networks, which consists of friendship or enmity relationships, is a model that relates the type of relationship between two people to the third p…
Heider Balance under Disordered Triadic Interactions
M. Bagherikalhor, A. Kargaran, A. H. Shirazi +1
The Heider balance addresses three-body interactions with the assumption that triads are equally important in the dynamics of the network. In many networks, the relations do not ha…
Heider and coevolutionary balance: From discrete to continuous phase transition
A. Kargaran, G. R. Jafari
Structural balance in social complex networks has been modeled with two types of triplet interactions. First, the interaction that only considers dynamic role for links or relation…
Mean-Field Solution for Critical Behavior of Signed Networks in Competitive Balance Theory
R. Masoumi, F. Oloomi, A. Kargaran +2
Competitive balance model has been proposed as an extension to the balance model to address the conflict of interests in signed networks arXiv:2001.04664 . In this model two differ…
Quartic Balance Theory: Global Minimum With Imbalanced Triangles
A. Kargaran, M. Ebrahimi, M. Riazi +2
Balance theory proposed by Heider for the first time modeled triplet interaction in a signed network, stating that relationships between two people, friendship or enmity, is depend…
