The project aims to describe emergent phenomena in low-dimensional systems, such as graphene, nanoribbons, and nanotubes, which require strong-interaction techniques due to their highly non-linear electronic behavior. These systems exhibit exotic phenomena tied to their underlying topology, resulting in topological insulators and superconductors, with potential applications in topological quantum computing. An Effective Field Theory (EFT) will be formulated to identify relevant degrees of freedom and investigate multi-particle dynamics. The project will use numerical simulations to determine Low-Energy Constants (LECs) for the EFT, considering length scales and non-locality of topological effects in different low-dimensional geometries.

The main goal of this project is to combine different methodologies effectively, leveraging their strengths against weaknesses. By integrating hybrid stochastic techniques with machine learning, multidimensional Tensor Networks, and the Iterative Configuration Expansion from quantum chemistry, our long term goal is to create a powerful approach to challenging quantum many-body systems. The objective is to unlock investigations of currently inaccessible quantum many-body systems at finite chemical potential, particularly focusing on QCD at finite baryon density and models for high-Tc superconductors.
