      abstract     = {We predict the existence of paramagnetic spin excitations
                      (PSE) in nonmagnetic single adatoms. Our calculations
                      demonstrate that PSE develop a well-defined structure in the
                      meV region when the adatom’s Stoner criterion for
                      magnetism is close to the critical point. We further reveal
                      a subtle tunability and enhancement of PSE by external
                      magnetic fields. Finally, we show how PSE can be detected as
                      moving steps in the dI/dV signal of inelastic scanning
                      tunneling spectroscopy, opening a potential route for
                      experimentally accessing electronic properties of
                      nonmagnetic adatoms, such as the Stoner parameter.},
