U.S.-Netherlands Cooperative Research: Quantum Coherence inFluids and Solids at Ultralow Temperatures

该奖项支持佛罗里达大学微开尔文研究实验室的Mark W. Meisel教授与荷兰莱顿大学Kamerlingh Onnes实验室的Georgio Frossati教授和其他超低温组成员在低温物理和低温工程研究方面的合作。提出的物理研究将集中在超流体氦-3的相边界和极化以及正常液体和超流体氦-3的高度极化形式的研究中涉及的几个难题。他们在低温工程方面的努力将解决在连续和脉冲超高磁场中实现超低温的问题，以及设计用于将纯氦-3/氦-4混合物冷却到迄今为止无法达到的低温的热交换器。​实验超低温物理领域，就其本质而言，无论是物理领域还是低温工程领域，都需要高度重视和创新思维。拟议的国际合作将两个领先的超低温研究小组联系起来，他们对追求科学和技术来解决该领域的基本问题感兴趣。联合起来，他们将处于更有利的地位，以设计新的方法来解决需要新技术来推进最先进技术的问题。

This award supports Professor Mark W. Meisel of the Microkelvin Research Laboratory at the University of Florida to collaborate in low temperature physics and cryogenic engineering research with Professor Georgio Frossati and others of the Ultralow Temperature Group at the Kamerlingh Onnes Laboratorium of the University of Leiden, Netherlands. The proposed research in physics will focus on several difficult problems associated with the study of phase boundaries and polarization in superfluid Helium-3 and highly polarized forms of normal liquid and superfluid helium-3. Their efforts in cryogenic engineering will address the problems of achieving ultralow temperature in continuous and pulsed ultra-high magnetic fields and on the design of heat exchangers which are tuned to cool pure Helium-3/Helium-4 mixtures to heretofore unattainable low temperatures. The field of experimental ultralow temperature physics, by its nature, requires careful attention and innovative thought in both physics and cryogenic engineering. The proposed international collaboration links two leading ultra-low temperature research groups which are interested in pursuing both the science and the technology necessary to attack fundamental problems in this field. Together, they will be in an even stronger position to design new approaches to questions that require novel techniques to advance the state-of-the-art.
