Abstract
To explain superconductivities and make up for the lack of current theory, a new quantum theory of cold electron was proposed. The key point is that we accepted the concept of electron orbital rotation instead of traditional electron spin. It leads to an important conclusion that the electron at low temperature is running in a flat orbital. The physical mechanism of superconductivities is so explained preferably. Under the assumption that the electrons have their motion tracks and the tracks can be described in atoms, the situations of electron will be changed a lot. The new concept of cold electron is then established. It means that the electrons can feel temperature. The Schrodinger function is the function of ideal electron indeed. Hot electron looks like the electron of the ideal electron. As temperature goes much lower, the electron orbits will obviously departure to what Schrodinger function described, and run in a flat one. The orbital shape of paired electron depends on temperature, transitioning from three- to two-dimension. Comparing the orbital shape to that of common electron, the paired cold electron saved quite some space in atomic crystal lattice. It created the preconditions for the phase transition at low critical temperature.

Superconductivity means that no electrical resistance appears when a special material was under low critical temperature, Tc
How to judge and treat the traditional quantum mechanics? Our opinion in this paper insist on that the great achievements of quantum mechanics and its theoretical system is beyond doubt; abandon this for other attempting theory is lifeless and inadvisable in field of superconductivity
It make us to rethink why can the Bohr atomic model explain the hydrogen spectral series accurately to be regarded as a wrong thing at starting point, complain why we have to temporarily abandon the description of pure wave quantum mechanics for explaining the general dispersion force between all of molecules, worry the unsolved physical mechanism of the formation of light polarizability and the elliptic polarization, and look back the embarrassed issue we faced in electron spin
Summary
Superconductivity means that no electrical resistance appears when a special material was under low critical temperature, Tc. (2015) Cold Electron Quantum Mechanical Model for Superconductivity. Many events have arisen to be landmarks of great significance in science [1], namely Tc as 4.2 K in mercury (Kamerlingh Onnes, 1911), 23.2 K in Nb-Ge alloy (Gavaler, 1973), 35 K in La-Ba cuprate (Miiller & Bednorz, 1986), 93 K in Y-Ba cuprate (C.W. Chu, 1987; Z.X. Zhao, 1987), 125 K in Tl-Ba-Ca cuprate (Z.Z. Sheng, 1988), 135 K in Hg-Ba-Ca cuprate The London model and G-L theory are good macroscopic quantum theory, but they explain the superconductivity with the lack of mechanism. The BCS theory as a microscopic theory explained the formation of Cooper pair of electron, but failed in its mechanism of electron-phonon interaction when Tc is higher than 40 K. We proposed a new concept of “cold electron” in order to reveal the nature of superconductivity
