Theory of Electronic Ferroelectricity
T. Portengen, Th. Ostreich, L. J. Sham
We present a theory of the linear and nonlinear optical characteristics of the insulating phase of the Falicov-Kimball model within the self-consistent mean-field approximation. Th…

Linear and nonlinear optical characteristics of the Falicov-Kimball model
T. Portengen, Th. Ostreich, L. J. Sham
We calculate the linear and nonlinear optical properties of the Falicov-Kimball model for a mixed-valent system within the self-consistent mean-field approximation. Second-harmonic…
