Quasi-1-Dimensional Superconductivity in Highly Disordered NbN Nanowires

Autor: Arutyunov, K. Yu., Ramos-Álvarez, A., Semenov, A. V., Korneeva, Yu. P., An, P. P., Korneev, A. A., Murphy, A., Bezryadin, A., Gol'tsman, G. N.

The topic of superconductivity in strongly disordered materials has attracted a significant attention. In particular vivid debates are related to the subject of intrinsic spatial inhomogeneity responsible for non-BCS relation between the superconduct

Coherent dynamics and decoherence in a superconducting weak link

Autor: Peltonen, J. T., Peng, Z. H., Korneeva, Yu. P., Voronov, B. M., Korneev, A. A., Semenov, A. V., Gol'tsman, G. N., Tsai, J. S., Astafiev, O. V.

Publikováno v: Phys. Rev. B 94, 180508 (2016)

We demonstrate coherent dynamics of quantized magnetic fluxes in a superconducting loop with a weak link - a nanobridge patterned from the same thin NbN film as the loop. The bridge is a short rounded shape constriction, close to 10 nm long and 20 -

Report

Energy-gap dynamics of superconducting NbN thin films studied by time-resolved terahertz spectroscopy

Autor: Beck, M., Klammer, M., Lang, S., Leiderer, P., Kabanov, V. V., Gol'tsman, G. N., Demsar, J.

Using time-domain Terahertz spectroscopy we performed direct studies of the photoinduced suppression and recovery of the superconducting gap in a conventional BCS superconductor NbN. Both processes are found to be strongly temperature and excitation

Report

Single photonics at telecom wavelengths using nanowire superconducting detectors

Autor: Zinoni, C., Alloing, B., Li, L. H., Marsili, F., Lunghi, L., Gerardino, A., Vakhtomin, Yu. B., Smirnov, K. V., Gol'tsman, G. N., Fiore, A.

Single photonic applications - such as quantum key distribution - rely on the transmission of single photons, and require the ultimate sensitivity that an optical detector can achieve. Single-photon detectors must convert the energy of an optical pul
