The group is formed by an interdisciplinary scientific team at the Universitat de Barcelona and at the Universitat Rovira i Virgili in Tarragona. The core of our work is the study of complex systems, particularly focusing on coupled systems, which represented one of the most active research areas of modern physics in recent years. Dynamical processes on these systems involve self-organization of individual components that interact with each other to form patterns or structures independently, without direct human intervention. In this sense, the process of genesis of coupled systems follows certain rules determined by the interactions between components, resulting in the spontaneous development of structures with functions and properties that can be very different from elementary components. Therefore, the coupling process is responsible for the appearance of emergent properties that can have a high level of complexity. This substrate of nontrivial coupling between the elements is what we call complex networks.
