石墨烯等离子体提供了贵金属等离子体的合适替代品，因为它们表现出更严格的限制和相对较长的传播距离，并且具有通过静电选通高度可调的优点。在这里，我们建议使用石墨烯等离子体作为一个平台，以强烈增强光-物质相互作用。具体地说，我们预测了在碳片附近的量子发射体的前所未有的高衰减率，可观察到的真空拉比分裂，以及超过石墨烯纳米带和纳米盘几何面积的消光截面。我们的理论结果为石墨烯等离子体的新兴和潜在的深远领域提供了基础，为腔量子电动力学提供了一个理想的平台，并支持了单分子、单等离子体器件的可能性。
Graphene plasmons provide a suitable alternative to noble-metal plasmons because they exhibit much tighter confinement and relatively long propagation distances, with the advantage of being highly tunable via electrostatic gating. Here, we propose to use graphene plasmons as a platform for strongly enhanced light-matter interactions. Specifically, we predict unprecedented high decay rates of quantum emitters in the proximity of a carbon sheet, observable vacuum Rabi splittings, and extinction cross sections exceeding the geometrical area in graphene nanoribbons and nanodisks. Our theoretical results provide the basis for the emerging and potentially far-reaching field of graphene plasmonics, offering an ideal platform for cavity quantum electrodynamics, and supporting the possibility of single-molecule, single-plasmon devices.
