Abstract
Complex systems are characterized by phenomena emerging in the hierarchy of scales far from those describing the numerous individual components. Such phenomena, which have a variety of origins, have repeatedly attracted the attention of the scientific community. Irrespective of the inherent diversity, some common concepts and principles are shared across different topics. Uncovering and understanding this richness requires the development of an integrative theoretical approach, capable of dealing with many-body problems across different fields. In this light, the main purpose of the present project is to enforce such a broad strategy by choosing problems that are highly relevant in current international research endeavors, while simultaneously maintaining a close connection with experimental results. The project addresses phenomena that emerge in systems characterized by strong interactions, disorder and/or the absence of equilibrium. The objects of the proposed research range from specific materials, the investigation of which is on the forefront of condensed matter research, to biological systems, functioning in their natural environment as physical systems far from equilibrium. The project is organized into work packages (WPs), each of which focuses on one important aspect of many-body systems exhibiting emergent phenomena. These are strong interactions, disorder and out-of-equilibrium dynamics. Each WP is organized around a series of different tasks, which, while WP-specific, share a significant degree of complementarity, ensuring coherence and interconnectedness across the WPs. Besides specific scientific contributions, the project aims to provide a significant consolidation of theoretical investigations at the Institute of Physics, including an improved environment for young researchers. The HrZZ’s support of the project is therefore of crucial importance for maintaining the international competitiveness of team members and for future perspectives.
