Electronic correlations are a central theme in contemporary condensed matter physics – and hold promise for new functionality in quantum materials.

Electronic excitations and vibrations of molecules can be efficiently excited by light thanks to the action of optical resonators which improve the interaction between light and matter.

Electron recollision in an intense laser field gives rise to a variety of phenomena, ranging from electron diffraction to coherent soft X-ray emission.

The prediction and subsequent discovery of robust spin-polarized surface states on topological band insulators has launched a new subfield of physics over the last decade.

Can we prolong the coherence of a two-state manifold in a complex quantum system beyond the coherence of its longest-lived component? This question is the starting point in the construction of a scalable quantum computer.
