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…
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…
Study of the skin effect in superconducting materials
Jacob Szeftel, Nicolas Sandeau, Antoine Khater
The skin effect is analyzed to provide the numerous measurements of the penetration depth of the electromagnetic field in superconducting materials with a theoretical basis. Both t…
On the physical significance of London's equation
Jacob Szeftel, Nicolas Sandeau, Antoine Khater
The Meissner effect is analysed by using an approach based on Newton and Maxwell's equations, in order to assess the relevance of London's equation. The Hall effect is predicted. T…
Comparative study of the Meissner and skin effects in superconductors
Jacob Szeftel, Nicolas Sandeau, Antoine Khater
The Meissner effect is studied by using an approach based on Newton and Maxwell's equations. The objective is to assess the relevance of London's equation and shed light on the con…
