TLDR
In this paper, the spontaneous decay rate of an excited atom placed near a dielectric cylinder is investigated, and the main contribution to decay rates is due to the quasistatic interaction of the atom dipole momentum with the nanofiber.Abstract:
The spontaneous decay rate of an excited atom placed near a dielectric cylinder is investigated. Special attention is paid to the case when the cylinder radius is small in comparison with radiation wavelength (nanofiber or photonic wire). In this case, the analytical expressions of the transition rates for different orientations of a dipole are derived. It is shown that the main contribution to decay rates is due to the quasistatic interaction of the atom dipole momentum with the nanofiber, and the contributions of guided modes are exponentially small. On the contrary, in the case when the radius of the fiber is only slightly less than the radiation wavelength, the influence of guided modes can be substantial. The results obtained are compared with the case of a dielectric nanospheroid and an ideally conducting wire.read more

Quantum optics with surface plasmons.
TL;DR: A technique that enables strong, coherent coupling between individual optical emitters and guided plasmon excitations in conducting nanostructures at optical frequencies is described and it is shown that under realistic conditions optical emission can be almost entirely directed into the plAsmon modes.

Colloquium: Quantum matter built from nanoscopic lattices of atoms and photons

Cavity QED with atomic mirrors
TL;DR: In this paper, the authors describe a technique to achieve strong coherent coupling between a single atom and a single photon in such a system, which makes use of collective enhancement effects, which allows a lattice of atoms to form a high-finesse cavity within the fiber.

Spontaneous emission of a cesium atom near a nanofiber: Efficient coupling of light to guided modes
TL;DR: In this article, the spontaneous emission of a cesium atom in the vicinity of a subwavelength-diameter fiber was studied and it was shown that the confinement of the guided modes and the degeneracy of the excited and ground states substantially affect spontaneous emission process.

TL;DR: In this paper, the authors investigate the feasibility of achieving electrically driven lasing from individual nanowires and show that these structures can function as Fabry-Perot optical cavities with mode spacing inversely related to the nanowire length.

Carbon nanotubes as molecular quantum wires
Abstract: Carbon nanotubes are cylindrical molecules with a diameter of as little as 1 nanometer and a length up to many micrometers They consist of only carbon atoms, and can essentially be thought of as a single layer of graphite that has been wrapped into a cylinder, (See figure 1 and the article by Thomas Ebbesen in PHYSICS TODAY, June 1996, page 26)

TL;DR: A redshift that is strongly dependent on pump power supports the idea that the electron–hole plasma mechanism is primarily responsible for the gain at room temperature and is a considerable advance towards the realization of electron-injected, nanowire-based ultraviolet–blue coherent light sources.

Quantum Theory of Radiation
TL;DR: For example, in this article, Dirac's concept was used to explain the problem of interference in the creation of a defense against nuclear radii. And Dirac succeeded in constructing a theoretic framework to solve the problem.
