Weak-coupling Treatment of Electronic (Anti-)Ferroelectricity in the Extended Falicov-Kimball Model

Claudia Schneider, Gerd Czycholl

We study the (spinless) Falicov-Kimball model extended by a finite band width (hopping ) of the localized (f-) electrons in infinite dimensions in the weak-coupling limit of a…
