Numerical studies of the photoluminescence spectrum of quantum Hall systems
- Tennessee Univ., Knoxville, TN (United States). Dept. of Physics and Astronomy
The eigenfunctions and eigenvalues of a system consisting of a finite number of electrons on a two dimensional plane together with a few holes on a neighboring plane are obtained by numerical diagonalization within the subspace of the lowest Landau level. The energy spectrum and ground state energy per particle are studied as a function of the Landau level degeneracy and the interlayer separation. By evaluating the square of the matrix element of the luminescence operator between the initial state with N{sub e} electrons and one hole and various final states with N{sub e} - 1 electrons and no hole, and multiplying by a delta function which conserves energy, the luminescence intensity I({omega}) is obtained.
