C. Micheletti et al., A COMPLETE DEVILS STAIRCASE IN THE FALICOV-KIMBALL MODEL, Journal of physics. A, mathematical and general, 30(21), 1997, pp. 711-717
We consider the neutral, one-dimensional Falicov-Kimball model at zero
temperature in the limit of a large electron-ion attractive potential
, U. By calculating the general n-ion interaction terms to leading ord
er in 1/U we argue that the ground state of the model exhibits the beh
aviour of a complete devil's staircase.
