Abstract:It was recently shown that the optical excitation of rare-earth ions produces a local change of the host matrix shape, attributed to a change of the rare-earth ion's electronic orbital geometry. In this work we investigate the consequences of this piezoorbital backaction and show from a macroscopic model how it yields a disregarded ion-ion interaction mediated by mechanical strain. This interaction scales as 1/r 3 , similarly to the other archetypal ion-ion interactions, namely electric and magnetic dipole-dip… Show more
