我们提出了在整数量子霍尔边态中产生和检测分数电荷激发的方法。电荷分馏是由于在不同边缘通道上传输的电子之间的库仑相互作用而发生的。在时间分辨或随频率变化的散粒噪声测量中，可以观察到类孤子集体激发的分数电荷。
We propose ways to create and detect fractionally charged excitations in integer quantum Hall edge states. The charge fractionalization occurs due to the Coulomb interaction between electrons propagating on different edge channels. The fractional charge of the solitonlike collective excitations can be observed in time-resolved or frequency-dependent shot noise measurements.
