Description:
Author(s): S. Ejima, T. Kaneko, Y. Ohta, and H. Fehske Using exact numerical techniques, we investigate the nature of excitonic (electron-hole) bound states and the development of exciton coherence in the one-dimensional half-filled extended Falicov-Kimball model. The ground-state phase diagram of the model exhibits, besides band-insulator and staggered... [Phys. Rev. Lett. 112, 026401] Published Mon Jan 13, 2014
