他们建议测量超流氦3的绝对热力学相图,主要集中在超流A和B相之间转变的磁场和压力依赖关系。从这项测量中,他们将能够提取有关超流体的热力学和微观数据,这是迄今为止无法获得的。他们进一步建议继续进行已经在进行的测量,研究超流氦3中由不受限制的几何结构的织构转变引起的超流极限。最后,他们建议继续研究在超低温下二维导电系统中失去平衡的电子的热化率。
英文摘要
They propose to measure the absolute thermodynamic phase diagram of superfluid Helium three, focusing principally upon the magnetic field and pressure dependences of the transition between the superfluid A and B phases. From this measurement they will be able to extract thermodynamic as well as microscopic data on the superfluid which has been unavailable to date. They further propose to continue measurements already in progress studying the limits to superflow in superfluid Helium three caused by textural transitions in unrestricted geometries. Finally they propose to continue their study of the thermalization rate of electrons taken out of equilibrium in two dimensional conducting systems at ultralow temperatures.
