论文摘要
我们开发了与量子发射器和外部电磁场相互作用的表面等离子体的一致量子描述。在分散和吸收培养基中宏观电动动力学的框架内，我们在马尔可夫近似，典型的哈密顿量，换向关系和耦合参数中，用于等离子体模式，其特征性大小低于差异限制的金属型结构中的金属型结构。然后，我们开发了一种新的量子方法，该方法桥接了宏观和规范方案，该方案用线性分散体描述了相互作用的等离子，该模式与线性分散剂相关，其耦合与电磁场和量子发射器是由经典等离子体介导的。通过准确考虑培养基分散体和表面等离子体与光和局部电子激发的相互作用中的损失，该方法可以作为研究血浆中非马克维亚效应的框架。
We develop a consistent quantum description of surface plasmons interacting with quantum emitters and external electromagnetic field. Within the framework of macroscopic electrodynamics in dispersive and absorptive medium, we derive, in the Markov approximation, the canonical Hamiltonian, commutation relations, and coupling parameters for the plasmon modes in metal-dielectric structures of an arbitrary shape whose characteristic size is well below the diffraction limit. We then develop a new quantum approach bridging the macroscopic and canonical schemes which describes the interacting plasmons in terms of bosonic modes with linear dispersion whose coupling to the electromagnetic field and quantum emitters is mediated by the classical plasmons. By accurately accounting for medium optical dispersion and losses in the interactions of surface plasmons with light and localized electron excitations, this approach can serve as a framework for studying non-Markovian effects in plasmonics.
