Experimental Studies of Superfluid Helium Three

建议继续进行超流氦3热力学性质的高精度测量计划。设想了四项研究：1)解决静态(SQUID)和动态(核磁共振)技术在A-B相变时磁化不连续性测量之间的差异。2)解决了A相的微观序参数是什么的问题。3)深入研究最近发现的A-B相变过热现象的本质。4)继续努力对A阶段的流体动力学测量数据进行数值模拟。

It is proposed to continue a program of high-precision measurements of the thermodynamic properties of superfluid helium three. Four studies are envisaged: 1) Resolve the discrepancy between measurements of the magnetization discontinuity at the A-B transition made by static (SQUID) and dynamic (NMR) techniques. 2) Settle the issue of what is the microscopic order parameter of the A phase. 3) Pursue study of the nature of the recently-discovered phenomenon of superheating of the A-B phase transition. 4) Continue our effort to numerically model our measurements of hydrodynamics in the A phase.
