Our framework combines the single-particle tight-binding approach with a nonlinear master equation formalism that captures both optical and electronic interactions We apply the framework to demonstrate the impact of electron tunneling between the adatom and the flake on emblematic quantum optical phenomena: degradation of coherent Rabi oscillations and quenching of Purcell spontaneous emission enhancement in two-level adatoms in proximity of triangular graphene nanoflakes. This work presents a framework for describing the electron dynamics in hybrid systems consisting of triangular graphene nanoflakes coupled both electronically and optically to adatoms and subject to external illumination. However, tunneling is usually not considered in quantum plasmonic approaches that focus on the optical coupling mechanism between quantum emitters and nanoantennas. LOCALIZED OPTICAL PHENOMENA AND THE CHARACTERIZATION OF MATERIALS INTERFACES. One or two, up to twenty or thirty, can appear at once. This paper presents the results of investigations of diffraction phenomena, complementary color behavior, Rayleigh scattering and optical activity in. Size ranges from candle flame to the size of a human, or larger. To exploit the field enhancement, quantum emitters such as atoms or molecules should be positioned in such close proximity to the flake that electron tunneling might influence the optical and electronic properties of the system. During the last decade, new unusual physical phenomena have been discovered in studying the optics of dielectric mesoscale particles of an arbitrary. Onibi a collection of atmospheric ghost lights supposed to occur in natural spaces, primarily blue luminescent orbs, sometimes also bluish white, red, and yellow. Graphene flakes acting as photonic nanoantennas sustain strong electromagnetic field localization and enhancement.
