Description:
Author(s): B. Zenker, D. Ihle, F. X. Bronold, and H. Fehske Based on the SO(2) -invariant slave-boson scheme, the static charge, orbital, and excitonic susceptibilities in the extended Falicov–Kimball model are calculated. Analyzing the phase without long-range order, we find instabilities toward charge order, orbital order, and the excitonic insulator (EI) p... [Phys. Rev. B 83, 235123] Published Mon Jun 13, 2011
