Quantum Systems on Surfaces

Welcome to our Lab

Our research activities are focused on atomic and molecular quantum systems on surfaces. In particular, we are interested in their magnetic (spin) properties for quantum applications. For details, see our mission statement below. Our lab was founded in 2020 by a Emmy-Noether Research grant from which it expands, among other with the ERC Starting Grant ATOMQUANT in 2024. We are located at the Physikalische Institut at the Karlsruhe Institute of Technology (KIT) in Karlsruhe in the State of Baden-Württemberg – right at the heart of Europe.

Mission Statement

As a team, we are on a mission. We describe our Why, What and How in the following statement: 

„We are excited to dive into the world of atoms and molecules, uncovering the mysteries of the nanoworld. In a diverse but like-minded team, we embrace the challenge of exploring and using the smallest building blocks of condensed matter. Our work with atoms and molecules advances our understanding of atomic structures, magnetism, quantum science and technology. This drives us to continuously innovate and refine our instrumentations with a focus on scanning probe microscopy.“
