Non-Technical Description:This grant supports a workshop on September 21-22, 2017 in Alexandria, Virginia. The workshop discusses frontier areas of materials research, especially quantum phenomena and quantum matter, that will open up if magnetic fields well beyond the current state-of-the art become available. The workshop facilitates interaction, knowledge exchange, and collaboration among participants. The discussions focus on the challenges in the research field, as well as how the materials research community can better articulate the importance of the quantum phases of matter accessible in strong magnetic fields. High magnetic fields have major impacts in many areas of fundamental research, as well as applied areas such as medical technology, transportation, and power generation.Technical Description:High magnetic fields have led to a large body of exciting results in quantum matter. Examples include quantum Hall effects and the rich assortments of many-body states at distinct fractional fillings, new Landau level phenomena in graphene, novel dimer states in quantum magnets, novel excitations in topological quantum matter, and vortex liquid states in cuprate superconductors. This workshop discusses scientific frontiers that will be opened up if magnetic fields beyond the current state-of-the art (45 tesla for stead-state field and 100 tesla for pulsed filed) become available. The scientific case for having a new large-scale instrument/facility that includes high magnetic fields is discussed.

非技术描述：这笔赠款支持2017年9月21日至22日在弗吉尼亚州亚历山大市举行的研讨会。研讨会讨论了材料研究的前沿领域，特别是量子现象和量子物质，如果磁场远远超过目前最先进的水平，这些领域将被打开。研讨会促进了参与者之间的互动、知识交流和合作。讨论的重点是研究领域的挑战，以及材料研究界如何更好地阐明在强磁场中可获得的物质的量子相的重要性。强磁场在许多基础研究领域以及医疗技术、交通、发电等应用领域都有重大影响。技术描述：强磁场导致了量子物质的一大批令人兴奋的结果。例如量子霍尔效应和不同分数填充处丰富的多体状态，石墨烯中新的朗道能级现象，量子磁体中新的二聚态，拓扑量子物质中的新激发，以及铜酸盐超导体中的涡旋液态。本研讨会讨论的是，如果有超过当前最先进水平的磁场(45特斯拉用于稳态场，100特斯拉用于脉冲场)，将开辟的科学前沿。讨论了建立包含强磁场的新型大型仪器/设施的科学依据。
