スポンサーリンク
概要
- 論文の詳細を見る
The exchange-scattering spectra are reproduced by the numerical calculation for the finite Heisenberg ladder with 12×2 sites. We adopt the continued-fraction to the calculation of the spectral function in the process of the Lanczos method. The result suggests that the characteristic structure appearing at 4 or 5 times the spin-gap. The calculation is compared with recent Raman Spectra observed in Sr_<14-x>Ca_xCu_<24>O_<41>.
