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.

实验将通过使用UCLA和莫斯科亚损伤中心中心开发的补充实验技术在毫米和亚毫升波光谱范围内进行。 重点放在超导和密度波状态下的费米液体中各种高度相关固体的电动力学上。 这些实验有望提供有关单个粒子和集体激发的重要信息。 通过利用两个机构可用的补充仪器，将在UCLA和莫斯科通用物理研究所和莫斯科通用物理研究所进行光学实验。 在不同温度下，将检查几种新型材料的光学电导率和介电性能。 还将开发将能够测量光学特性的新方法。
