标题： Single quasiparticle and electron nano-emitter in the fractional quantum Hall regime

摘要： 我们提出一种装置，该装置由一个在时间上由磁场周期驱动的反点组成，作为著名的基于介观电容器的单电子源的分数量子霍尔效应对应物。 我们全面表征该装置作为向Laughlin序列的分数量子霍尔边缘通道发射单独准粒子和电子的理想发射器。 我们的分析基于主方程方法，并确定了两种类型源的最佳操作区域。 准粒子/准空穴发射区域实际上只涉及反点的两个电荷状态，从而允许解析处理。 我们展示了发射电荷的精确量化，确定了其最佳工作区域，并计算了逃逸时间从发射器中的函数关系的相位噪声/散粒噪声交叉。 需要更大驱动幅度的电子发射要求对主方程进行完整的数值处理，因为涉及更多的准粒子电荷状态。 然而，在这种情况下，也可以实现每周期发射一个电子电荷后跟一个空穴，并且噪声谱的整体形状与准粒子源相似，但额外的准粒子过程的存在会增强噪声幅度。 显示英文摘要

摘要： We propose a device consisting in an antidot periodically driven in time by a magnetic field as a fractional quantum Hall counterpart of the celebrated mesoscopic capacitor-based single electron source. We fully characterize the setup as an ideal emitter of individual quasiparticles and electrons into fractional quantum Hall edge channels of the Laughlin sequence. Our treatment relies on a master equation approach and identifies the optimal regime of operation for both types of sources. The quasiparticle/quasihole emission regime involves in practice only two charge states of the antidot, allowing for an analytic treatment. We show the precise quantization of the emitted charge, we determine its optimal working regime, and we compute the phase noise/shot noise crossover as a function of the escape time from the emitter. The emission of electrons, which calls for a larger amplitude of the drive, requires a full numerical treatment of the master equations as more quasiparticle charge states are involved. Nevertheless, in this case the emission of one electron charge followed by one hole per period can also be achieved, and the overall shape of the noise spectrum is similar to that of the quasiparticle source, but the presence of additional quasiparticle processes enhances the noise amplitude.
