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…
An observable prerequisite for the existence of persistent currents
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous
A classical model is presented for persistent currents in superconductors. Their existence is argued to be warranted because their decay would violate the second law of thermodynam…
