摘要:
等离激元是金属中自由电子的集体振荡,其在物理,生物、化学、能源、信息等领域具有重要的应用前景。近些年来对等离激元量子效应研究的深入开展使得等离激元研究迈入了新阶段。本文首先简要介绍了等离激元的两个基本特性:光压缩效应和局域电场增强效应;随后回顾了量子等离激元方面的最新的进展,包括量子纠缠效应,量子尺寸效应,量子遂穿效应,等离激元在台阶势垒处的反射与激发,等离激元对电子相干效应的增强;最后对量子等离激元研究进行了总结和展望。

Abstract:
Plasmon is the collective oscillation of electrons in metals , which possesses broad application prospects in physics, biology, chemistry, energy, information and so on. Recently, plasmonic behaviors have been proposed and observed in the quantum regime, opening a new avenue of research on quantum plasmonics. In this review, we first introduce some basic properties of plasmon as well as their relevant applications. Next, we review some latest progresses on quantum plasmonics, including quantum entanglement, quantum size effect, quantum reflection at the potential steps, and plasm on enhancement of quantum coherence. Finally, we give a summary and outlook of quantum plasmonics.
Key words:  plasmon, light compression, enhancement of local electric field, quantum plasmonics, quantum entanglement, size effect, potential step, electron coherence length
