Research Areas

At the interface between two materials, emergent phenomena can appear that are more than the sum of their parts. We are interested to create these interfaces and investigate such phenomena out of curiosity for basic science, and also because they will form the building blocks for future quantum technologies.

Interfaces based on chiral topological semimetals

Recently, we discovered that chiral topological semimetals can host new fermionic quasiparticles that are elusive in high-energy physics, which carry the largest topological charge that can exist in nature. Their interfaces may be very useful for spintronics applications and catalysis. We are one of the world leading groups in this nascent field of research and plan to further investigate and utilize these novel materials.

Semiconductor-superconductor interfaces for topological qubits

Semiconductor-superconductor interfaces have been predicted to be one of the most promising platforms for the realization of Majorana zero modes for topological quantum computation. We are closely collaborating with the Microscoft Quantum Materials Lab in Copenhagen and other partners from around the world to make this prediction a reality.

Interfaces made from (twisted) 2D materials

Interfaces made from materials that are only few monolayers thick have been demonstrated to host a variety of fascinating phenomena, such as electronic flat bands that can give rise to superconductivity, correlated insulators, or magnetism. We will synthesise our own 2D interfaces and work with partners from MPI Halle and around the world to further elucidate and exploit the microscopic mechanism behind these phenomena.
