Presidential Faculty Fellows

94-53362 Broholm这个校长奖将支持一个项目，涉及凝聚态系统中量子现象的中子衍射研究。该项目有很强的教育成分，涉及本科生和研究生的研究。该研究解决了所谓的量子无序固体的结构和磁性秩序，这些固体仅在零温度极限下表现出磁性相变。该体系包括一维线性链、二维反铁磁片、重费米子金属和过渡金属氧化物。这项研究不仅具有重要的基础意义，而且具有潜在的技术重要性，因为它可能为高温超导等相关领域提供启示。该奖项将支持一个研究具有量子效应的材料的磁性和电学性质的项目。该项目有很强的教育成分，涉及本科生和研究生的研究。这项研究旨在研究只有当材料达到“绝对零度”时才会出现的相变。这与非量子材料形成对比，如冰，经历了普通的相变，融化温度为32华氏度。这些系统包括线性链或磁性原子的二维阵列、复杂的金属合金和过渡金属氧化物。这项研究不仅具有重要的基础意义，而且具有潜在的技术重要性，因为它可能为高温超导等相关领域提供启示。

94-53362 Broholm This Presidential Faculty Fellow award will support a project involving neutron diffraction investigations of quantum phenomena in condensed matter systems. The project has a strong educational component which involves both undergraduate and graduate students in the research. The research addresses structural and magnetic order in so-called quantum disordered solids that only exhibit a magnetic phase transition in the limit of zero temperature. The systems include one-dimensional linear chains, two-dimensional antiferromagnetic sheets, heavy-Fermion metals and transition- metal oxides. The research is of considerable fundamental interest, but has potential technological importance since it may shed light on related fields such as high temperature superconductivity. This Presidential Faculty Fellow award will support a project to study magnetism and electrical properties of materials which exhibit quantum effects. The project has a strong educational component which involves both undergraduate and graduate students in the research. The research seeks to study phase transitions that only emerge as the materials reach "absolute zero". This can be contrasted with non-quantum materials such as ice that undergoes an ordinary phase transition, melting a 32 F. The systems include linear chains or two-dimensional arrays of magnetic atoms, complex metal alloys and transition-metal oxides. The research is of considerable fundamental interest, but has potential technological importance since it may shed light on related fields such as high temperature superconductivity.
