项目摘要
9503009 Gruner This project investigates the surface electrodynamic response of metallic systems referred to as charged quantum liquids. The experiments are unique in that they probe a broad frequency range, at low temperatures, where deviations from conventional Fermi liquid behavior can be pronounced. The experiments will provide important tests of theories of non-Fermi liquids. The project involves low temperatures, to 0.35 Kelvin, and high magnetic fields, to 9 Tesla. The materials to be investigated include UPt3, a conventional Fermi liquid, and suspected non-Fermi liquid alloys, cerium-copper-gold and uranium-yttrium-palladium, as well as two-dimensional organic metals. The work is of fundamental interest, but the results may also bear on other important non-Fermi liquid materials such as the high temperature superconductors. %%% This project looks at the response of unusual metallic systems, including so-called organic metals, to a broad range of electromagnetic radiation (light). The response to the radiation is measured at very low temperatures and at very high magnetic fields. The motivation of the work is to understand differences in the response of these materials as compared to ordinary metals, whose electrical properties are much better understood. The experiments are technically complex and can only be carried out in a few laboratories in the world. The materials to be investigated include UPt3, a conventional metallic material, the suspected non-conventional metal alloys: cerium-copper-gold and uranium-yttrium-palladium, as well as two-dimensional "organic" metals. The work is of fundamental interest, but the results may also bear on other important non-Fermi liquid materials such as the high temperature superconductors. ***
9503009 Gruner该项目研究被称为带电量子液体的金属系统的表面电动力学响应。这些实验的独特之处在于,它们在低温下探测了广泛的频率范围,在这种情况下,可以明显地偏离传统的费米液体行为。这些实验将为非费米液体的理论提供重要的检验。该项目涉及到0.35开尔文的低温和9特斯拉的高磁场。 待研究的材料包括UPt 3,一种传统的费米液体,和可疑的非费米液体合金,铈-铜-金和铀-钇-钯,以及二维有机金属。 这项工作是基本的兴趣,但结果也可能对其他重要的非费米液体材料,如高温超导体。 这个项目着眼于不寻常的金属系统,包括所谓的有机金属,对广泛的电磁辐射(光)的反应。在非常低的温度和非常高的磁场下测量对辐射的响应。 这项工作的动机是了解这些材料与普通金属相比在响应方面的差异,普通金属的电性能更容易理解。这些实验技术复杂,只能在世界上少数几个实验室进行。待研究的材料包括UPt 3,一种传统的金属材料,可疑的非传统金属合金:铈-铜-金和铀-钇-钯,以及二维“有机”金属。这项工作是基本的兴趣,但结果也可能对其他重要的非费米液体材料,如高温超导体。 ***
