摘要

等离子体-金属中光与自由电子的相互作用-通常在经典电动力学中使用局部响应本构定律(如欧姆定律)来理解。然而，等离子体对小体积的紧密局域化揭示了有趣的新物理学，如等离子体的非局部响应的非经典电动力学。在不同的电荷传导材料系统中，从亚10纳米贵金属颗粒到掺杂石墨烯的单原子薄片，都在理论和实验上探索了非局部效应。

Classical and quantum effects in noble metal and graphene plasmonics

Plasmonics - the interaction of light with free electrons in metals - is commonly understood within classical electrodynamics using local-response constitutive laws (such as Ohm's law). However, the tight localization of plasmons to small volumes is revealing intriguing new physics such as nonclassical electrodynamics with a nonlocal response of the plasmons. Nonlocal effects are being explored both theoretically and experimentally in different charge-conducting material systems with examples ranging from sub-10 nanometer noble metal particles to one-atom thin disks of doped graphene.
