Reconstructing the bulk Fermi surface and superconducting gap properties from neutron scattering experiments
Reconstructing the bulk Fermi surface and superconducting gap properties from neutron scattering experiments
We develop an analytical tool to extract bulk electronic properties of unconventional superconductors from inelastic neutron scattering spectra. We show that the upward and downward branches of the spin excitation spectra have distinct origins, with the upper branch representing a gapped spin-wave dispersion and the lower branch associated with Bogoliubov …
