The optical properties of superconductors, in particular the real parts of the conductivity and the dielectric function, may be used to calculate the strength of the condensate. In systems where all the free carriers collapse into the condensate, this approach works well. However, in gapless systems, and in unconventional systems in which the superconducting energy gap is observed to have zeros...
We have used aqueous dispersions of silver nanowires to prepare thin, flexible, transparent, conducting films. The nanowires are of length and diameter close to 6.5 μm and 85 nm, respectively. At low thickness, the films consist of networks but appear to become bulk-like for mean film thicknesses above ∼160 nm. These films can be very transparent with optical transmittance reaching as high as 9...
While optical techniques are fundamental in the investigation of superconducting state, many clean superconductors combination particle-hole and inversion symmetries prevents momentum-conserving transitions. Here, authors show that by driving supercurrent through sample transitions across gap become allowed even single-band systems. As signal depends strongly on pairing as well underlying norma...
