Superconductivity in simple metals

Abstract

The superconducting state parameters for both nomuperconductors and simple-metal (nontransition-metal) superconductors are evaluated using the exact OPW (orthogonalizedplane-wave) form-factors based on the model pseudopotential of Heine and Abarenkov. An attempt is made to establish a criterion for the occurrence of superconductivity in nontransition metals using the pseudopotential approach and it is inferred that more reliable values of the superconducting state parameters can be obtained using a correct pseudopotential and the phonon spectrum Die Supraleitungszustandsparameter werden sowohl fiir Nichtsupraleiter als auch einfache Metallsupraleiter (Nicht-tfbergangsmetalle) mit den exakten OPW(orthogone1ized plane-wave)-Formfaktoren auf der Basis des Modellpotentials von Heine und Abarenkov berechnet. Es wird der Versuch gemacht, ein Kriterium fiir das Auftreten von Supraleitfihigkeit in Nicht-tfbergangsmetallen mit der Pseudopotentialbehandlung aufzustellen. Es wird gefolgert, daD zuverliissige Werte fiir die Supraleitungszustandsparameter mit einem korrekten Pseudopotential und dem Phononenspektrum erhalten werden konnen.

Superconductivity in the elements, alloys and simple compounds

“…To learn what has been achieved since then in that respect we looked at all the papers citing these seminal works. There are a few more recent calculations of T c 's of elements that report improved agreement with experiment [83][84][85][86][87][88][89][90][91]. However, by and large the interest of the leading practitioners of this science/art and their disciples shifted to calculate critical temperatures of more complicated materials, some of which will be discussed in other papers in this Special Issue.…”
