Collective action through adaptive awareness

Afolabi Ariwayo, Bryce Morsky, Malbor Asllani

Collective actions emerge through the interplay between social influence and awareness. We introduce a nonlinear opinion-dynamics framework on networks in which social influence, s…

The Frequency Response of Networks as Open Systems

Amirhossein Nazerian, Malbor Asllani, Melvyn Tyloo +2

Many biological, technological, and social systems can be effectively described as networks of interacting subsystems. Typically, these networks are not isolated objects, but inter…

Extreme vulnerability to intruder attacks destabilizes network dynamics

Amirhossein Nazerian, Sahand Tangerami, Malbor Asllani +3

Consensus, synchronization, formation control, and power grid balance are examples of desirable dynamical states that arise in networks. Here we investigate how such states can be…

Explosive opinion spreading with polarization and depolarization via asymmetric perception

Haoyang Qian, Malbor Asllani

Polarization significantly influences societal divisions across economic, political, religious, and ideological lines. Understanding these mechanisms is key to devising strategies…

Towards a Theory for the Formation of Chimera Patterns in Complex Networks

Malbor Asllani, Alex Arenas

Chimera states, marked by the coexistence of order and disorder in systems of coupled oscillators, have captivated researchers with their existence and intricate patterns. Despite…

Broken detailed balance and entropy production in directed networks

Ramón Nartallo-Kaluarachchi, Malbor Asllani, Gustavo Deco +3

The structure of a complex network plays a crucial role in determining its dynamical properties. In this work, we show that the the degree to which a network is directed and hierar…

Emergence of power-law distributions in self-segregation reaction-diffusion processes

Jean-François de Kemmeter, Adam Byrne, Amy Dunne +2

Many natural or human-made systems encompassing local reactions and diffusion processes exhibit spatially distributed patterns of some relevant dynamical variable. These interactio…
