项目摘要

This proposal requests funds to support a research team of graduate students and undergraduates to work on several of challenging measurements. My philosophy is to identify open questions that can be answered with improved and innovative measurement techniques. For example by setting up ultra low temperature specific heat measurements we have identified previously undetected phase transitions in frustrated magnetic materials. Another example is developing a new photon detector that can be multiplexed to large number of pixel arrays and can be optimized for a large range of energy (from sub-mm to x-ray). These detectors (Kinetic inductance detectors) are now being developed for state-of-the-art telescope cameras but can be adapted to other applications such as x-ray detectors for medical research. My group works on superconducting quantum interference devices (SQUIDS). These are the most sensitive magnetic field sensors, with this we customize measurements to detect subtle magnetic properties of novel materials. We are studying the magnetic properties of a fascinating and complex systems of frustrated magnetic materials that can be candidates for new classes of magnetic state (quantum spin liquids). In all these projects we collaborate with experts, either theorists that specialize in magnetic materials, crystal growers and neutron scatterers that have complimentary measurements and interests, or astrophysicists that have a different and complimentary background.

该提案要求资金支持由研究生和本科生组成的研究团队进行一些具有挑战性的测量，我的理念是找出可以通过改进和创新的测量技术来回答的开放性问题，例如通过设置超低温比热。另一个例子是开发一种新的光子探测器，它可以多路复用到大量像素阵列，并且可以针对大范围的能量（从亚毫米到 X 射线）进行优化。）。这些探测器（动感电感探测器）目前正在为最先进的望远镜相机开发，但也可以适用于其他应用，例如用于医学研究的 X 射线探测器。是最灵敏的磁场传感器，我们通过定制测量来检测新型材料的微妙磁特性，我们正在研究令人着迷且复杂的受挫磁性材料系统的磁特性，这些材料可以成为新型磁态（量子）的候选者。旋转在所有这些项目中，我们与专家合作，这些专家要么是专门研究磁性材料、晶体生长者和中子散射者的具有互补测量和兴趣的理论家，要么是具有不同且互补背景的天体物理学家。
