Neutron resonant spin-echo spectroscopy and neutron/x-ray contrast reflectometryOur group operates the neutron resonant spin-echo spectrometer TRISP and the neutron/x-ray contrast reflectometer NREX at the FRM-II neutron source in Garching near Munich. Our recent research focused on the combined effects of the electronic structure and lattice vibrations on superconductivity in lead and niobium, the non-Fermi liquid state in MnSi, the physics of spin fluctuations in the prototypical antiferromagnet MnF2, and several other physical problems, where the unprecedentedly high μeV-resolution of TRISP proved indispensable.

Recent highlight
The locus of Kohn anomalies extracted from the jumps in the longitudinal phonon
linewidths in the (hk0) and (hhl) planes in Pb (blue points),
compared to the constant-energy cut of the lowest-energy transverse acoustic
phonon branch at 2.8 meV ± 10% (red lines).
