项目摘要
The ground state and thermally and optically excited states in halogen-bridged Pd/Ni mixed-metal complexes have been studied theoretically for various mixing ratios. The main results are:1.The Raman data behaviors when the mixing ratio is changed continuously are well explained by the present theory.2.Using the DMRG method, the effects of electron correlation is identified as giving a abrupt change of states from CDW to a Mott insulator. This tendency is consistent with the experimentally measured metal valencies.3.The photoinduced effects are identified as bi-directional ones, namely, CDW to Mott insulator transitions in a CDW-rich phase, and Mott-insulator to CDW transitions in a Mott-insulator-rich phase. Our final estimation is that one excited pair of an electron and a hole yields a phase conversion of 20 sites on the average.
本文从理论上研究了不同配比下卤素桥接Pd/Ni混合金属配合物的基态、热激发态和光学激发态。主要结果是:1。该理论很好地解释了混合比连续变化时的拉曼数据行为。利用DMRG方法,确定了电子相关的影响是导致从CDW到Mott绝缘体的状态突变。这种趋势与实验测量的金属价相一致。光致效应是双向的,即CDW在富CDW相中向Mott绝缘子转变,Mott绝缘子在富Mott绝缘子相中向CDW转变。我们的最终估计是,一个电子和一个空穴的一个激发态对平均产生20个位相转换。
