      abstract     = {We provide experimental evidence for the absence of a
                      magnetic moment in bulk RuO$_2$, a candidate altermagnetic
                      material, by using a combination of Mössbauer spectroscopy,
                      nuclear forward scattering, inelastic X-ray and neutron
                      scattering, and density functional theory calculations.
                      Using complementary Mössbauer and nuclear forward
                      scattering, we determine the Ru magnetic hyperfine splitting
                      to be negligible. Inelastic X-ray and neutron
                      scattering-derived lattice dynamics of RuO$_2$ are compared
                      to density functional theory calculations of varying
                      flavors. Comparisons among theory with experiments indicate
                      that electronic correlations, rather than magnetic order,
                      are key in describing the lattice dynamics.},
