论文摘要
我们报告了分数量子霍尔（QH）准颗粒在石墨烯解毒剂上的定位。通过在解毒剂上的局部QH边缘模式下研究相干隧道，我们测量了QH准粒子费用约为$ \ pm E/3 $，分数为$ν= \ pm 1/3 $。石墨烯中的狄拉克光谱允许大量能量尺度和稳健的准粒子定位，以防止热激发。将分数准粒子定位在QH解毒剂上的能力带来了实现Anyon编织和新型量子电子产品的有希望的机会。
We report localization of fractional quantum Hall (QH) quasiparticles on graphene antidots. By studying coherent tunneling through the localized QH edge modes on the antidot, we measured the QH quasiparticle charges to be approximately $\pm e/3$ at fractional fillings of $ν= \pm 1/3$. The Dirac spectrum in graphene allows large energy scales and robust quasiparticle localization against thermal excitation. The capability of localizing fractional quasiparticles on QH antidots brings promising opportunities for realizing anyon braiding and novel quantum electronics.
