Gz. Wen et Wp. Su, DENSITY-MATRIX RENORMALIZATION-GROUP CALCULATION OF OPTICAL-ABSORPTION IN CONJUGATED POLYMERS, Synthetic metals, 85(1-3), 1997, pp. 1041-1042
We report our study of dimerized extended-Hubbard chains. Density matr
ix renormalization group (DMRG) method is employed to calculate ground
state and excited state absorption spectra.
