Collective oscillations driven by correlation in the nonlinear optical regime
Th. Oestreich, L. J. Sham
We present an analytical and numerical study of the coherent exciton polarization including exciton-exciton correlation. The time evolution after excitation with ultrashort optical…

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…
