WebIn weak-coupling d-wave theory, such a high-frequency upturn may be due to the presence of inelastic scatterers (e.g., spin fluctuations [4,16]), or from the breaking of Cooper pairs in a d-wave superconductor [15]. In either case, conductivity in the super-conducting state is expected to reach the normal state value WebBCS Theory and Superconductivity 1. Introduction Superconductivity discovered in 1911 by Onnes (9), is the quantum phenomena that certain materials exhibit un-der particular …
WebIn the s wave BCS theory, because pairs can be thermally excited across the gap Δ, the change in superfluid density per unit change in temperature goes as exponential behavior, exp (-Δ/ kBT ). In that case, the penetration depth … WebJul 8, 2024 · Abstract. We study order parameter fluctuation effects in the superconducting state as a possible precursor to the pseudogap phenomena. Using a low-energy effective theory in the d-wave BCS model, we self-consistently calculate the single-particle properties.We find that the fluctuations reduce the spectral gap, and the shape of the gap …

Cooper showed such binding will occur in the presence of an attractive potential, no matter how weak. In conventional superconductors, an attraction is generally attributed to an electron-lattice interaction. The BCS theory, however, requires only that the potential be attractive, regardless of its origin.
