结果表明，总填充nu=1的量子霍尔双层膜应该表现出类似于大约瑟夫森结中的磁通流动的动力学机制。这种类比可以解释层间隧道电导[Phys.莱特牧师。84,5808(2000)]。在低偏置电压下，磁通流很可能是时空混沌的，这将通过宽带噪声表现出来。峰的位置可以由面内磁场控制。
We show that a quantum Hall bilayer with the total filling nu = 1 should exhibit a dynamical regime similar to the flux flow in large Josephson junctions. This analogy may explain a conspicuous peak in the interlayer tunneling conductance [Phys. Rev. Lett. 84, 5808 (2000)]. The flux flow is likely to be spatiotemporally chaotic at low-bias voltage, which will manifest itself through broadband noise. The peak position can be controlled by an in-plane magnetic field.
