Edge magnetoplasmon is an emergent chiral bosonic mode promising for studying electronic quantum optics. While the plasmon transport has been investigated with various techniques for decades, its coupling to a mesoscopic device remained unexplored. Here, we demonstrate the coupling between a single plasmon mode in a quantum Hall plasmon resonator and a double quantum dot (DQD). Resonant plasmon-assisted tunneling is observed in the DQD through absorbing or emitting plasmons stored in the resonator. By using the DQD as a spectrometer, the plasmon energy and the coupling strength are evaluated, which can be controlled by changing the electrostatic environment of the quantum Hall edge. The observed plasmon-electron coupling encourages us for studying strong coupling regimes of plasmonic cavity quantum electrodynamics.

耦合到量子霍尔等离子体谐振器的双量子点中的谐振等离子体辅助隧道效应
边缘磁等离子是一种新兴的手性玻色子模式,有望用于研究电子量子光学。虽然几十年来人们已经用各种技术研究了等离子体传输,但它与介观装置的耦合仍未得到探索。在这里,我们演示了量子霍尔等离子体谐振器中的单等离子体模式与双量子点(DQD)之间的耦合。通过吸收或发射谐振器中存储的等离激元,在 DQD 中观察到共振等离激元辅助隧道效应。通过使用DQD作为光谱仪,评估等离子体激元能量和耦合强度,这可以通过改变量子霍尔边缘的静电环境来控制。观察到的等离子体-电子耦合鼓励我们研究等离子体腔量子电动力学的强耦合机制。
