我们研究了耦合量子线系统中的输运，并展示了共振相互作用的证据，每当其中一条偏置接近掐断时，就会发生共振相互作用。测量其中一根导线的电导，当另一根导线的宽度变化时，我们观察到电导中的谐振峰与另一根导线夹断的点相关。这种相互作用的起源目前仍未确定，尽管其特征似乎与预测一致，即当电导消失时，窄线中应该形成相关的多体状态。
We study the transport in a system of coupled quantum wires and show evidence for a resonant interaction that occurs whenever one of them is biased close to pinch off. Measuring the conductance of one of the wires, as the width of the other is varied, we observe a resonant peak in the conductance that is correlated to the point at which the other wire pinches off. The origin of this interaction remains undetermined at present, although its characteristics appear consistent with predictions that a correlated many-body state should form in narrow wires as their conductance vanishes.
