      abstract     = {We report first principles calculations of the structural
                      parameters and phonon dispersion of the
                      tetragonalnoncentrosymmetric heavy fermion compound CeAuAl3.
                      Taking into account weak magnetoelastic interactionsof the
                      rare-earth (RE) ions with the spectrum of phonons, we obtain
                      an analytical expression for the hybridizationof quadrupole
                      excitations and phonons from the poles of the one-phonon
                      Green function. In the paramagneticphase, we predict the
                      formation of mixed modes that may be observed by inelastic
                      neutron scattering. Our resultsshow that magnetoelastic
                      interactions, albeit being moderate, play an important role
                      in CeAuAl3. This suggeststhat magnetoelastic interactions
                      may be equally important in a wide range of related
                      compounds.},
