Subharmonic gap structure in d-wave superconductors
We present a self-consistent theory of current-voltage characteristics of d-wave/d-wave contacts at arbitrary transparency. In particular, we address the open problem of the observation of subharmonic gap structure ~SGS! in cuprate junctions. Our analysis shows that ~i! the SGS is possible in d-wave superconductors; ~ii! the existence of bound states within the gap results in an even-odd effect...
متن کاملPlasma Oscillations in Layered Superconductors
Very soon after publication of the famous BCS work explaining the puzzle of the superconductivity, N.N. Bogolyubov and coworkers [1] have proposed their version of the theory. One of new results they have obtained was the discovery of a collective mode an oscillation of the Cooper pair density with the energy smaller than 2∆. P.W. Anderson has indicated that this collective mode can not be foun...
متن کاملMagnetization Relaxation in Layered Superconductors
The energy of a pointlike vortex is calculated for a layered superconductor with very weak interlayer Josephson coupling. An energy barrier existing near the sample surface is found. Magnetization relaxation due to thermally activated penetration of pointlike vortices and quantum tunnelling of pointlike vortices are considered. An initial avalanche-type decay of magnetization is predicted. Magn...
متن کاملAnomalous Fluxon Properties of Layered Superconductors
Highly anisotropic layered superconductors can be considered as stacks of Josephson junctions (SJJ’s) [1, 2]. The key feature of SJJ’s is mutual coupling of junctions, which can be achieved via magnetic [3, 4], charging [5, 6] or nonequilibrium [7] coupling mechanisms. Properties of SJJ’s can be qualitatively different from that of single Josephson junctions (JJ’s) or anisotropic type-II superc...
متن کاملContinuous Ginzburg–Landau description of layered superconductors
The behaviour of the order parameter and its effects in intrinsically-layered superconductors are studied within a continuous Ginzburg–Landau model. A simple model of interlayer coupling is proposed in which we suggest that the coupling strength between superconducting and insulating layers may be qualitatively described by a reciprocal of a difference between the order parameters at the respec...
