A New Physical Picture of Pairing Mechanism in Superconductors: Could the Electron be a Composite Particle?

Abstract

The physical pictures of the electron pairing structure and pairing mechanisms in superconductors are reviewed. An initial idea for a new physical picture of the origin and nature of the pairing is proposed. The idea is based on the assumption that the electron is no longer a single fundamental but a composite particle. This property is hidden in the normal state. How a natural pairing could occur in the superconducting state and the processes closely related to this change inside the atom are developed in a new physical picture with new insight(although it needs verification and real evidence for now). An attempt, to show that a zero resistance to a direct current and Josephson effects could be used as example evidences for this assumption, is presented by means of this new insight in general schematical analogy. A possible new research direction, hopefully to achieve room temperature superconductors, is suggested as a consequence.Comment: 17 pages, 12 figures, 46 Reference
