Experiments will be conducted in the millimeter and submillimeter wave spectral range by using complementary experimental techniques developed at UCLA and at the Institute of General Physics, Center for Submillimeter Radiophysics, Moscow. The focus is on the electrodynamics of various highly correlated solids in their Fermi liquid, in the superconducting and density wave states. These experiments are expected to give important information on both single particle and collective excitations. %%% Optical experiments will be conducted at UCLA and at the Institute of General Physics, Moscow, over a broad frequency spectrum by utilizing complementary instruments available at the two Institutions. The optical conductivity and dielectric properties of several new types of materials will be examined at different temperatures. New methods which will enable the measurement of optical characteristics will also be developed.

实验将利用加州大学洛杉矶分校和莫斯科亚毫米放射物理中心普通物理研究所开发的互补实验技术在毫米波和亚毫米波光谱范围内进行。 重点是费米液体中各种高度相关固体在超导和密度波状态下的电动力学。 这些实验有望提供有关单粒子和集体激发的重要信息。 %%% 光学实验将在加州大学洛杉矶分校和莫斯科普通物理研究所利用两个机构提供的互补仪器在广泛的频谱上进行。 将在不同温度下检查几种新型材料的光电导率和介电性能。 还将开发能够测量光学特性的新方法。
