“…Light scattering from metals can be governed by the excitation of bulk or surface plasmons. In particular, a spherical nanoparticle has a peak in the absorption cross-section when Re(ε) = -2 [63] owing to a localized surface plasmon (LSP) resonance [87,88]. The resonances also occur for non-spherical particles with geometrical factors determining the resonant values of Re(ε), which are on the order of unity for realistically attainable aspect ratios.…”

Abstract:The excitation of surface-phonon-polariton (SPhP) modes in polar dielectric crystals and the associated new developments in the field of SPhPs are reviewed. The emphasis of this work is on providing an understanding of the general phenomenon, including the origin of the Reststrahlen band, the role that optical phonons in polar dielectric lattices play in supporting sub-diffraction-limited modes and how the relatively long optical phonon lifetimes can lead to the low optical losses observed within these materials. Based on this overview, the achievements attained to date and the potential technological advantages of these materials are discussed for localized modes in nanostructures, propagating modes on surfaces and in waveguides and novel metamaterial designs, with the goal of realizing low-loss nanophotonics and metamaterials in the mid-infrared to terahertz spectral ranges.

“…The result is that the positive and negative branches of S(ω) are related to the emission and absorption spectrum, respectively. Concerning the emission processes, if the source of noise is the system biased by a voltage V , intuitively one expects that the maximum energy available for the tunneling electron is eV , and, thus, the energy of an emitted photon is limited to eV as well, as shown by several experiments and theoretical investigations [5][6][7][8][9][10][11][12][13][14][15] . Such inelastic effects in tunneling junctions are interesting because they can help to reveal unusual phenomena like electron-electron correlation and electron-plasmon effects.…”

Inelastic tunneling of electrons can generate the emission of photons with energies intuitively limited by the applied bias voltage. However, experiments indicate that more complex processes involving the interaction of electrons with plasmon polaritons lead to photon emission with overbias energies. We recently proposed a model of this observation in Phys. Rev. Lett. 113, 066801 (2014), in analogy to the dynamical Coulomb blockade, originally developed for treating the electromagnetic environment in mesoscopic circuits. This model describes the correlated tunneling of two electrons interacting with a local plasmon-polariton mode, represented by a resonant circuit, and shows that the overbias emission is due to the non-Gaussian fluctuations. Here we extend our model to study the overbias emission at finite temperature. We find that the thermal smearing strongly masks the overbias emission. Hence, the detection of the correlated tunneling processes requires temperatures kBT much lower than the bias energy eV and the plasmon energy ω0, a condition which is fortunately realized experimentally.
