Geometrical theory of the shift current in presence of disorder and interaction
Raffaele Resta
The electric field of light induces--in a non centrosymmetric insulator--a dc current, quadratic in the field magnitude, and called "shift current". When addressed from a many-elec…

Electron Localization in the Insulating State
R. Resta, S. Sorella
The insulating state of matter is characterized by the excitation spectrum, but also by qualitative features of the electronic ground state. The insulating ground wavefunction in f…

Non-Nominal Value of the Dynamical Effective Charge in Alkaline-Earth Oxides
M. Posternak, A. Baldereschi, H. Krakauer +1
We calculate ab-initio the electronic states and the Born dynamical charge Z* of the alkaline-earth oxides in the local-density approximation. We investigate the trend of increasin…
