Polariton dispersion in nanocomposite materials

Polaizability and susceptibility in the valley orbit split states in an intense field

“…The values of the above quantities diverge as MIT is approached [5][6][7][8][9][10][11]. The reason for the non-consideration of these values in the excited valley -orbit split states are (1) the absence of a proper many valley effective mass theory [12][13] and (2) the shift of interest to low-dimensional semiconductor systems in the last three decades [14][15][16][17][18][19][20][21][22].…”
