Energy Gaps and Kohn Anomalies in Elemental Superconductors
P. Aynajian, T. Keller, L. Boeri +2
The momentum and temperature dependence of the lifetimes of acoustic phonons in the elemental superconductors Pb and Nb was determined by resonant spin-echo spectroscopy with neutr…

Spin-Wave Lifetimes Throughout the Brillouin Zone
S. P. Bayrakci, T. Keller, K. Habicht +1
We use a neutron spin-echo method with eV resolution to determine the lifetimes of spin waves in the prototypical antiferromagnet MnF over the entire Brillouin zone. A theor…
