SFB 484: Cooperative Phenomena in Solids:Metal-Insulator Transitions and Ordering of Microscopic Degrees of Freedom

484合作研究中心致力于固态物理学中量子力学、多粒子系统中的合作现象的研究。激发研究的基本问题可以表述如下：电子和晶格的微观自由度的相互作用和集体行为如何导致有序现象和金属-绝缘体转变？过渡金属氧化物是分析这些问题的理想材料类别，因此代表了正在研究的系统的基础。在这一领域的综合研究是通过结合固体物理学和材料科学学科的研究活动来实现的。应用最现代的实验和理论方法，合作研究中心打算研究上述现象的微观基础，同时建立与应用导向的主题的联系。该研究中心由12个分项目组成，平均分为实验和理论研究。

The collaborative research centre 484 focusses on the investigationof cooperative phenomena in quantum-mechanical, many-particle systems in solid-state physics. The basic question motivating the research may be formulated as follows: how do the interaction and collective behavior of the microscopic degrees of freedom of electrons and lattice lead to ordering phenomena and metal-insulator transitions? The transition-metal oxides are the ideal class of materials to analyse these questions, and hence represent the basis for the systems under investigation. A comprehensive study in this field is effected by combining research activities in the disciplines of solid-state physics and materials science. Applying the most modern experimental and theoretical methods the collaborative research centre intends to examine the microscopic foundations of the above phenomena and, simultaneously, establish connections with application-oriented topics. The research centre consists of twelve subprojects which are divided evenly between experimental and theoretical research.
