Query: High Resolution Study of Spin Excitations in the Shastry-Sutherland
  Singlet Ground State of SrCu2(BO3)2   High resolution, inelastic neutron scattering measurements on SrCu2(BO3)2
reveal the dispersion of the three single triplet excitations continuously
across the (H,0) direction within its tetragonal basal plane. These
measurements also show distinct Q dependencies for the single and multiple
triplet excitations, and that these excitations are largely dispersionless
perpendicular to this plane. The temperature dependence of the intensities of
these excitations is well described as the complement of the dc-susceptibility
of SrCu2(BO3)2.
