我们研究了由一对分裂门量子点形成的开放量子点分子在低温磁导中观察到的涨落特征。这些波动的演化表明，随着点耦合强度的降低，相干干涉的典型区域减少。我们根据从多点干涉到单点干涉的转变来讨论这一行为，作为点间耦合的函数。
We study the characteristics of the fluctuations, observed in the low-temperature magnetoconductance of an open quantum-dot molecule formed from a pair of split-gate quantum dots. The evolution of these fluctuations suggests a decrease in the typical area for coherent interference with decreasing dot-coupling strength. We discuss this behavior in terms of a transition from multi- to single-dot interference as a function of the interdot coupling.
