Jakob Lass

Jakob Lass is a Researcher at the Laboratory for Neutron Scattering and Imaging, Paul Scherrer Institute (PSI) in Switzerland, specializing in advanced neutron scattering techniques for quantum materials research. His work bridges experimental physics and computational tool development to probe complex magnetic phenomena.

His research focuses on condensed matter physics with emphasis on quantum magnetism, magnetic materials, and topological spin textures. Key areas include skyrmion phases in centrosymmetric metals, bond-dependent interactions in frustrated magnets, heavy fermion systems like UTe₂, and quantum critical phenomena. He develops critical software infrastructure such as DMCpy for neutron diffraction analysis and AMBER for spectrometer background estimation.

Analysis of his 2023-2025 publications reveals a dual focus: methodological innovation in neutron instrumentation (e.g., BIFROST spectrometer development, background reduction techniques) and fundamental discoveries in quantum materials (e.g., magnon band splitting in altermagnets, spin-flop transitions, and skyrmion formation mechanisms). His work frequently employs honeycomb lattice antiferromagnets and centrosymmetric metals as model systems.

Dr. Lass actively contributes to PSI's Laboratory for Neutron Scattering and Imaging, collaborating on international projects at facilities like the European Spallation Source. His team develops cutting-edge neutron spectrometry techniques while investigating exotic states of matter under extreme conditions including high magnetic fields and low temperatures.
