Application of mode coupling theory to group IVB liquids モード・カップリング理論のIVB族液体への応用 星野, 公三 下條, 冬樹 宗尻, 修治 Hoshino, Kozo Shimojo, Fuyuki Munejiri, Shuji モード・カップリング理論 液体Ge 液体Sn 液体Na 分子動力学シミュレーション 速度自己相関関数 数値解析 自己拡散 研究開発 液体金属 mode coupling theory liquid Ge liquid Sn liquid Na molecular dynamics simulation velocity autocorrelation function numerical analysis self diffusion research and development liquid metal The atomic dynamics of liquid Ge, Sn and Na are studied based on the mode coupling theory. The memory functions for the velocity autocorrelation functions (VAF) are obtained for liquid Ge, Sn and Na numerically from the VAF obtained by the molecular-dynamics simulations and are divided into the binary-collision term and the mode-coupling term. For the liquid Na the memory functions are also calculated theoretically by the mode-coupling theory and compared with that obtained numerically. The characteristic features of the memory functions for the liquid Ge and Sn near the triple point are qualitatively different from those for the typical liquids and are similar to those of the memory function of the liquid Na at high temperatures, which cannot be described by the mode-coupling theory. 資料番号: AA0033133003 レポート番号: NASDA-TMR-010019E 宇宙開発事業団 National Space Development Agency of Japan (NASDA) 2002-02-28 eng technical report https://jaxa.repo.nii.ac.jp/records/42608 1345-7888 Modeling and Precise Experiments of Diffusion Phenomena in Melts Under Microgravity: Annual Report 2000 55 63 https://jaxa.repo.nii.ac.jp/record/42608/files/33133003.pdf application/pdf 526.5 kB 2020-02-10
