Time-dependent electron current through a nanoscale phase-coherent quantum ring with leads, coupled to reservoirs biased by a sinusoidal voltage, is studied. We argue that Floquet states in such samples, driven also by external time-periodic magnetic field, can be coherently manipulated. Some examples show that on-demand structures in the frequency domain, tunable by the joint action of the voltage bias and a microwave pumping, can be generated this way.

纳米级量子环中的微波驱动恒流

研究了随时间流逝的电子流过带引线的纳米级相干量子环，并耦合到正弦电压偏置的储层。我们认为，此类样本中的浮球状态，也可以由外部时间周期磁场驱动，可以被相干地操纵。一些示例表明，可以通过这种方式生成频域中的按需结构，该结构可通过电压偏置和微波泵浦的联合作用进行调整。
