Quasi-Particle Dynamics in Low-Dimensional Topological Systems (B01)

• Subject Area: Theoretical Condensed Matter Physics ; Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 511713970

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.
