Disorder and Correlations in Novel Two-Dimensional Systems

主要目标是定量理解无序和电子-电子相互作用对喷射到固体氢上的电子输运性质的影响。研究了单电子局域化效应向无序维格纳晶体态的演化过程。第二个研究领域是被氢涂层逐渐光滑的无序表面上的超流动性的性质。降低一个系统的维数通常会给它的特性和行为带来深刻的变化。对这种变化的研究丰富了我们对量子力学和凝聚态物理的理解。

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.
