Theoretical research will be conducted on the properties of Fermi systems where the interparticle interactions or the lack of translational invariance gives rise to qualitatively new effects. The work is relevant to many systems of current experimental interest such as heavy Fermion compounds, liquid Helium three near solidification, high temperature superconductors, doped semiconductors, amorphous alloys and alkali-doped Fullerenes. The understanding of the thermodynamics and the transport properties of strongly interacting electrons in amorphous and crystalline solids is relevant to basic science and will ultimately lead to the design of technologically useful materials. %%% Theoretical research will be done on the behavior of electrons which interact strongly with each other. This is a very fundamental problem which remains unsolved. However, its solution will have major impacts on a variety of materials including the high temperature superconductors and the newly discovered superconducting Fullerenes.

我们将对费米系统的性质进行理论研究，其中粒子间的相互作用或平移不变性的缺乏会产生质的新效应。这项工作涉及当前许多实验感兴趣的系统，如重费米子化合物、液氦三近凝固、高温超导体、掺杂半导体、非晶态合金和碱掺杂富勒烯。对非晶态和晶态固体中强相互作用电子的热力学和输运性质的理解与基础科学有关，并最终将导致技术上有用的材料的设计。将对相互作用强烈的电子的行为进行理论研究。这是一个非常根本的问题，仍然没有解决。然而，它的解决方案将对各种材料产生重大影响，包括高温超导体和新发现的超导富勒烯。
