“…One important aspect of such an interaction is the resultant modification of the spontaneous emission rate of atoms located near nanobodies, such as dielectric nanofibers, nanospheres and nanodisks [1][2][3][4]. Fluorescence radiation emitted by excited atoms located near the nanobody and, subsequently, coupled into the nanobody [5,6] is another practically important aspect that should be considered.…”

We analyse the lineshape of the fluorescence emitted by a cloud of optically excited cold atoms and coupled into an optical nanofibre. We examine the efficiency of the fluorescence coupling and describe the asymmetry of the lineshape caused by the redshifts arising from both the van der Waals and Casimir–Polder interaction of the atoms with the surface of the optical nanofibre. We compare the contributions of the van der Waals and Casimir–Polder redshifts and show that the lineshape of the fluorescence coupled into an optical nanofibre is, basically, influenced by the van der Waals redshift and is characterized by a long tail on the red side of the spectrum. We conclude that a measurement of the lineshape of the coupled fluorescence could be used to characterize the strength of the interaction of atoms with dielectric surfaces and for the detection of atoms using nanofibres.

“…First investigation of the decay rate of an atom placed on the axis of dielectric fiber was undertaken within classical approach in [23][24]. Recently that problem attracted new interest [25][26][27][28]. In [29][30] spontaneous emission near carbon nanotubes was considered.…”

The spontaneous decay rates of an excited atom placed near a dielectric cylinder are investigated. A 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 dipole are derived. It is shown that the main contribution to decay rates is due to quasistatic interaction of atom dipole momentum with nanofiber and the contributions of guided modes are exponentially small. On the contrary, in the case when the radius of fiber is only slightly less than radiation wavelength, the influence of guided modes can be substantial. The results obtained are compared with the case of dielectric nanospheroid and ideally conducting wire.

“…They are a key component in recent considerations of atom chips [11], spontaneous decay rates and level shifts [12][13][14][15][16][17][18][19], zero-point energy [20], Casimir-Polder interactions [21][22][23], and intermolecular resonance energy transfer [24]. In all these works, the cylinders are assumed to be infinitely long.…”
