The activity in this field has been focused on the study of materials characterized by strong electron-phonon and electron-electron interactions with particular emphasis to perovskitic oxides of technological interest. The research themes can be summarized as follows:
Lanczos diagonalizations and optimized phonon basis for electron-phonon systems
Charge-ordered phases induced by electron-phonon coupling effects: Infrared absorption
Polaron properties in different electron-phonon models including optical conductivity
Spintronic devices have attracted the attention of many researchers for both fundamental physics and technological applications. The interest in this field has been focused on two questions.
Localization effects induced by spin-orbit coupling
Field-effect transistors for spin current: spin double refraction
Vortices play a crucial role in the physics of superconductors. At the present the activity is focused on vortex correlations in frustrated systems.
Cluster approachs and Percolation ideas have been applied successfully to many very different physical situations. We have focused our attention to the following two fields.
The main contribution has concerned the calculation of dispersion relation for edge-plasmons in two-dimensional metallic stripes and wedges including themagneti effect.
