Towards room-temperature superconductivity
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous +1
By taking advantage of a stability criterion established recently, the critical temperature is reckoned with help of the microscopic parameters, characterising the normal and…
Thermal Stability of Superconductors
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous +1
A stability criterion is worked out for the superconducting phase. The validity of a prerequisite, established previously for persistent currents, is thereby confirmed. Temperature…
A Novel Treatment of the Josephson Effect
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous
A new picture of the Josephson effect is devised. The radio-frequency (RF) signal, observed in a Josephson junction, is shown to stem from bound electrons, tunneling periodically t…
Comment on "`Inconsistency of the conventional theory of superconductivity"' by Hirsch J.E
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous +1
A rebuttal of a recent article by Hirsch J.E. is presented below. To begin with, the main assumption, regarding the Meissner effect, which the whole argument relies upon, is dispro…
Study of the superconducting to normal transition
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous
A model, based on classical mechanics and thermodynamics and valid for \textit{all} superconductors, is devised to investigate the properties of the \textit{current-driven}, superc…
Revisiting low-frequency susceptibility data in superconducting materials
Jacob Szeftel, Michel Abou Ghantous, Nicolas Sandeau
Old susceptibility data, measured in superconducting materials at low-frequency, are shown to be accounted for consistently within the framework of a recently published\cite{sz1} a…
