二维电子流体中可压缩性驱动的金属-绝缘体相变的标度理论

Scaling Theory of a Compressibility-Driven Metal-Insulator Transition in a Two-Dimensional Electron Fluid

D. Belitz, T. R. Kirkpatrick

摘要:

我们提出了一个缩放描述的金属-绝缘体过渡的二维电子系统,是由一个消失的压缩性,而不是消失的扩散系数。一小部分基本假设产生了一个一致的理论框架,该框架与现有的传输和压缩性测量兼容,并允许对其他可观测量进行预测。我们还讨论了这些想法和其他理论之间的联系过渡到不可压缩的量子流体。

英文摘要:

We present a scaling description of a metal-insulator transition in two-dimensional electron systems that is driven by a vanishing compressibility rather than a vanishing diffusion coefficient. A small set of basic assumptions leads to a consistent theoretical framework that is compatible with existing transport and compressibility measurements, and allows to make predictions for other observables. We also discuss connections between these ideas and other theories of transitions to an incompressible quantum fluid.
