Universal scaling in BCS superconductivity in three dimensions in non-s waves
(1998-12-01)
The solutions of a renormalized BCS equation are studied in three space dimensions in s, p and d waves for finite-range separable potentials in the weak to medium coupling region. In the weak-coupling limit, the present ...
Complexity and disequilibrium as telltales of superconductivity
(Elsevier Science, 2018-09)
We show that the statistical complexity and the disequilibrium are good indicators of the critical pairing coupling constant’s value that signals the onset of superconductivity, a well-known phase transition. This suggests ...
Non-Fermi-liquid superconductivity: Eliashberg approach versus the renormalization group
(American Physical Society, 2017-04)
We address the problem of superconductivity for non-Fermi liquids using two commonly adopted, yet apparently distinct, methods: (1) the renormalization group (RG) and (2) Eliashberg theory. The extent to which both methods ...
Superconductivity in nanocrystalline tungsten thin films growth by sputtering in a nitrogen-argon mixture
(Elsevier Science SA, 2019-06)
We report on the structural and superconducting properties of nanocrystalline tungsten thin films growth by sputtering at room temperature with an N2:Ar mixture (N2 from 3% to 50%). The crystalline phases were identified ...

Development on polymeric precursor routes to produce superconducting nanoparticles
(Elsevier B.V., 2007-09-01)
The well-known polymeric precursor route is a simple and low-cost sol-gel method based on the preparation of an aqueous precursor solution of metals followed by the addition of a water-soluble polymer. This method consists ...
