Laboratory for Advanced Spectroscopy and X-ray Sources
In the Laboratory for Advanced Spectroscopy and X-ray Sources (LSX), we develop and apply advanced spectroscopic techniques for condensed materials and related scientific domains. We study electronic structure, low-energy excitations, correlation effects and ultra-fast dynamics in a broad range of complex material systems. We also develop world-leading undulator X-ray sources for Synchrotron and X-ray free electron laser providing beams of unprecedented quality in terms of brilliance, peak intensity and pulse length.

Weyl spin-momentum locking in a chiral topological semimetal
Spin–orbit coupling in noncentrosymmetric crystals leads to spin–momentum locking – a directional relationship between an electron’s spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin–momentum locking has been studied for decades, while its counterpart, isotropic parallel Weyl spin–momentum locking has remained elusive in experiments. Theory predicts ...
Extreme ultraviolet for scalable silicon quantum devices
Experiments at the Swiss Light Source (SLS) show the potential of extreme ultraviolet light (EUV) to make the building blocks of scalable quantum computers.
The secret life of an electromagnon
SwissFEL sheds light on how lattice and atomic spins jiggle together.
