9712626 Si This is a grant to conduct theoretical research on the physics of metallic non-Fermi liquids in strongly correlated electron systems. Projects will include: non-Fermi liquid solutions to an extended Hubbard model; elucidation of the elementary excitations in non-Fermi liquid metals close to quantum phase transitions; and, a collaboration with an experimental program to study the electron-spin diffusion in the normal state of high temperature superconductors. %%% The theoretical research will study the behavior of electrons in metals in which the electrons are strongly interacting. In this case, the very concepts on which normal electrons behave in solids and the usual methods of analysis are called into question. This research will attempt to resolve some questions related to this very important problem which is of fundamental and practical interest. ***

9712626 Si这是一项资助，用于对强关联电子系统中金属非费米液体的物理进行理论研究。 项目将包括：非费米液体解决方案的扩展哈伯德模型;阐明非费米液体金属接近量子相变的基本激发;以及，与实验计划合作，研究高温超导体正常状态下的电子自旋扩散。 理论研究将研究电子在金属中的行为，其中电子相互作用很强。 在这种情况下，正常电子在固体中的行为所依据的概念和通常的分析方法都受到了质疑。 本研究将试图解决与这一非常重要的问题有关的一些问题，这是基本的和实际的利益。 ***
