The main goal is a quantitative understanding of the effects of disorder and electron-electron interactions on the transport properties of electrons sprayed on to solid hydrogen. The evolution of single-electron localization effects into the disordered-Wigner-Crystal state will be studied. A Second area of study is the nature of superfluidity on disordered surfaces that are progressively smoothed by coating with hydrogen. Reducing the dimensionality of a system usually introduces profound changes in its character and behavior. Studies of such changes enrich our understanding of quantum mechanics and condensed-matter physics.

主要目标是定量地了解 无序和电子间相互作用对输运的影响 喷射到固体氢上的电子的性质。 的 单电子局域化效应演变成 无序Wigner晶体态将被研究。 第二个研究领域是无序超流的性质。 通过涂上氢而逐渐平滑的表面。 降低系统的维数通常会引入深刻的 改变其性格和行为。 研究这些变化 丰富我们对量子力学和凝聚态的理解 物理学
