Kosterlitz-Thouless and Dimensionality Phenomena in Helium Films

在局域和超流体状态下，从2K到50mK，对二维氦膜进行了系统的量热研究，提出了对Kosterlitz-Thouless理论的确定测试。将采用各种基材。其次，将对多孔介质中的氦进行热导率测量，作为所涉及的机制的探针。

A systematic calorimetric study of 2D helium films in the localized and superfluid regimes, from 2K down to 50mK, is proposed for a definitive test of the Kosterlitz-Thouless theory. A variety of substrates will be employed. Secondly, thermal conductivity measurements will be made on helium in porous media, as a probe of the mechanism involved.
