Surface Josephson plasma waves in layered superconductors.
We predict the existence of surface waves in layered superconductors in the THz frequency range, below the Josephson plasma frequency omega J. This wave propagates along the vacuum-superconductor interface and dampens in both transverse directions out of the surface (i.e., towards the superconductor and towards the vacuum). This is the first prediction of propagating surface waves in any superc...
متن کاملJosephson Effect in Unconventional Superconductors
In this letter we present a simple relation, that allows one to predict the Josephson current between two unconventional superconductors with arbitrary band-structure and pairing symmetry. We illustrate this relation with examples of s-wave and d-wave junctions and show a detailed numerical comparison with the phenomenological Sigrist and Rice relation [1] commonly used to interpret tunneling e...
متن کاملOptical properties of crystals with spatial dispersion – Josephson plasma resonance in layered superconductors
– We derive the transmission coefficient, T (ω), for grazing incidence of crystals with spatial dispersion accounting for the excitation of multiple modes with different wave vectors k for a given frequency ω. The generalization of the Fresnel formulas contains the refraction indices of these modes as determined by the dielectric function ǫ(ω,k). Near frequencies ωe, where the group velocity va...
متن کاملExcitation of plasma oscillations by moving Josephson vortices in layered superconductors
Electric and magnetic fields created by moving uniform lattice of Josephson vortices in the magnetic field parallel to the layers are calculated in the frame of exactly solvable model. At large velocities of the vortex lattice the plasma oscillations of superconducting electrons are excited by vortex motion, this results in interference features in I-V curves at low temperatures. The spectrum o...
