U.S.-France Cooperative Research: Classical and Quantum Dynamics of Glassy Systems

[0089835]巴伦支这项为期三年的美法凝聚态理论合作研究奖的获得者包括加州大学圣巴巴拉分校的Leon M. Balents和他的团队，以及法国巴黎高等师范学院的Pierre Le Doussal和他的团队。研究人员建议扩展和应用材料的弹性模型来描述：II型超导体中的涡旋晶格；钉住电荷密度波和维格纳晶体；铁磁体中的畴壁；和量子霍尔双层层。将使用功能归一化群方法、量子输运方法和包含拓扑缺陷的方法。目的是对实验相关系统的粗化和老化进行更现实的描述，并利用这些模型探索量子区域的输运、耗散、非线性和玻璃动力学。这个美国小组为这次合作带来了无序系统方面的专业知识。他们将专注于量子输运和低维导体的应用以及其他效应。这是由法国小组在无序系统和他们的新技术来描述拓扑缺陷的专业知识补充。该奖项代表了美国方面向美国国家科学基金会和法国国家科学研究中心（CNRS）提出的联合提案。美国国家科学基金会国际项目部和材料研究部将承担美国研究员、博士后研究员和/或研究生的旅费和生活费。法国科学研究中心将支持法国研究人员访问美国。该合作将促进对现代材料的相互作用和无序以及材料的粗化和老化过程的基本理解。

0089835BalentsThis three-year award for U.S.-France cooperative research in condensed matter theory involves Leon M. Balents and his group at the University of California, Santa Barbara and Pierre Le Doussal and his group at the Ecole Normale Superieure in Paris, France. The investigators propose to extend and apply elastic models of materials that describe: vortex lattices in type II superconductors; pinned charge density waves and Wigner crystals; domain walls in ferromagnets; and quantum Hall bilayers. Functional normalization group methods, quantum transport methods and inclusion of topological defects will be utilized. The objective is to develop more realistic descriptions of coarsening and aging of experimentally relevant systems and use the models to explore transport, dissipation, non-linear and glassy dynamics in the quantum region. The US group brings to this collaboration expertise in disordered systems. They will focus on quantum transport and applications of low-dimensional conductors and other effects. This is complemented by expertise of the French group in disordered systems and their new techniques to describe topological defects. This award represents the US side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF's Division of International Programs and Division of Materials Research will cover travel funds and living expenses for the US investigator, postdoctoral researcher and/or graduate student. The CNRS will support the visits of French researchers to the United States. The collaboration will advance fundamental understanding of interactions and disorder in modern materials and the coarsening and aging process of materials.
