This award supports fundamental research and education in systems, which have topological quantum numbers. The proposed work is focussed on the dynamics of vortices in superfluids and superconductors, mechanisms for flux flow at low temperature, the structure of surfaces and interfaces of fractional quantum Hall phases, and the nature of transitions between quantum Hall phases. This award supports graduate education of students in condensed matter theory and theoretical research focussed on two important problems that lie at the frontiers of condensed matter theory that have a subtle geometric connection. These are the motion of vortices in superconductors, and phase transitions between novel quantum states that occur in electrons trapped at semiconductor interfaces in high magnetic fields.

该奖项支持具有拓扑量子数的系统的基础研究和教育。 拟开展的工作主要集中在超流体和超导体中的涡旋动力学、低温下磁通流动的机制、分数量子霍尔相的表面和界面结构以及量子霍尔相之间的跃迁性质。 该奖项支持学生在凝聚态理论和理论研究的研究生教育，重点是在凝聚态理论的前沿，有一个微妙的几何连接的两个重要问题。 这些是超导体中涡旋的运动，以及在强磁场中被困在半导体界面的电子中发生的新量子态之间的相变。
