Abstract
The optical conductivity of disordered one-dimensional Wigner crystal in gated semiconductors is studied using exact diagonalization techniques. Our model calculation shows that the optical conductivity develops two types of broadened peaks. The lower-energy peak is due to a wide distribution of local pinning frequencies while the higher-energy peak is due to the creation of pairs of solitons.
