二维量子电子液体的Corbino圆盘粘度计
A Corbino disk viscometer for 2D quantum electron liquids
摘要：
从超冷原子费米气体到夸克-胶子等离子体，各种强相互作用量子流体的剪切粘度都可以精确测量。相反，没有实验数据存在，据我们所知，在二维量子电子液体托管在固态矩阵的剪切粘度。在这封信中，我们提出了一个科尔比诺磁盘设备，它允许确定量子电子液体的粘度从直流电势差之间产生的内部和外部边缘的磁盘响应于振荡的磁通量。
英文摘要：
The shear viscosity of a variety of strongly interacting quantum fluids, ranging from ultracold atomic Fermi gases to quark-gluon plasmas, can be accurately measured. On the contrary, no experimental data exist, to the best of our knowledge, on the shear viscosity of two-dimensional quantum electron liquids hosted in a solid-state matrix. In this Letter we propose a Corbino disk device, which allows a determination of the viscosity of a quantum electron liquid from the dc potential difference that arises between the inner and the outer edge of the disk in response to an oscillating magnetic flux.
