Model for twin electromagnons and magnetically induced oscillatory polarization in multiferroic RMnO
Markku P. V. Stenberg, Rogerio de Sousa
We propose a model for the pair of electromagnon excitations observed in the class of multiferroic materials {\it R}MnO ({\it R} is a rare-earth ion). The model is based on a h…

Response functions of an artificial Anderson atom in the atomic limit
Ari T. Alastalo, Markku P. V. Stenberg, Martti M. Salomaa
We consider the spin and pseudospin (charge) response functions of the exactly soluble Anderson atom model. We demonstrate, in particular, that a deviation from the magnetic Curie-…
