Theoretical analysis of low-temperature quantum tunneling of hydrogen in Nb(OH)x

The authors of this paper present the research results of low temperature creep of AlMgSi (6101) wires and AAAC - All Aluminium Alloy Conductor. The conductor is made from AlMgSi wires (diameter 2.99 mm). Based on theoretical analysis it was proved that creep of an overhead conductors depends on the relation between stress and temperature of conductor and the span geometry. Thus the objective of the paper is to determine the wire and conductor creep under the conditions of stress drop. On the basis of the research it has been observed that the creep of both the AAAC conductor and the AlMgSi wires temporarily stopped.

AbstractPoint-contact Andreev-reflection (PCAR) experiments were performed in the Fe-1111 layered superconductor LaFeAsO0.9F0.1 with resistive T con âˆ¼ 27 K. The observation of two pairs of peaks in the low-temperature Andreev-reflection spectra clearly indicates the presence of two order parameters. The behavior of the two gaps as a function of temperature, obtained by fitting the conductance curves by means of the generalized two-band Blonder-Tinkham-Klapwijk model, shows some anomalies. A theoretical analysis performed within the two-band Eliashberg theory with a generic electron-boson coupling can reproduce the low-temperature value of the two gaps but generally fails in giving a satisfactory fit of their overall temperature dependence, indicating the rich and complex physics of these newly discovered superconductors.
