论文摘要
我们表明，使用近场光学元件可以通过利用超固定的石墨烯等离子体来使超导体的HIGGS模式通常具有挑战性。作为近场来源，我们研究了两个例子：石墨烯等离子和量子发射器。在这两种情况下，与希格斯模式的耦合都清晰可见。在石墨烯等离子的情况下，耦合是通过石墨烯等离子体与超导体HIGGS模式的相互作用的透明抗骨信号发出的。在量子发射器的情况下，可以通过Purcell效应观察到Higgs模式。在结合超导体，石墨烯和量子发射器时，许多实验旋钮可用于揭幕和研究超导体的电动力学。
We show that the Higgs mode of a superconductor, which is usually challenging to observe by far-field optics, can be made clearly visible using near-field optics by harnessing ultraconfined graphene plasmons. As near-field sources we investigate two examples: graphene plasmons and quantum emitters. In both cases the coupling to the Higgs mode is clearly visible. In the case of the graphene plasmons, the coupling is signaled by a clear anticrossing stemming from the interaction of graphene plasmons with the Higgs mode of the superconductor. In the case of the quantum emitters, the Higgs mode is observable through the Purcell effect. When combining the superconductor, graphene, and the quantum emitters, a number of experimental knobs become available for unveiling and studying the electrodynamics of superconductors.
