We report an Aharonov-Bohm superperiod of five magnetic flux quanta (5h/e) observed in a Laughlin quasiparticle interferometer, where an edge channel of the 1/3 fractional quantum Hall fluid encircles an island of the 2/5 fluid. This result does not violate the gauge invariance argument of the Byers-Yang theorem because the magnetic flux, in addition to affecting the Aharonov-Bohm phase of the encircling 1/3 quasiparticles, creates the 2/5 quasiparticles in the island. The superperiod is accordingly understood as imposed by the anyonic statistical interaction of Laughlin quasiparticles.
我们报告了在劳克林准粒子干涉仪中观测到的一个由五个磁通量量子（5h/e）构成的阿哈罗诺夫 - 玻姆超周期，其中1/3分数量子霍尔流体的一个边缘通道环绕着一个2/5流体的岛。这一结果并不违反拜尔斯 - 杨定理的规范不变性论点，因为磁通量除了影响环绕的1/3准粒子的阿哈罗诺夫 - 玻姆相位外，还在岛内产生了2/5准粒子。因此，该超周期被理解为由劳克林准粒子的任意子统计相互作用所施加。
