Double Time

The defect-induced anharmonic phonon-electron problem in high-temperature superconductors has been investigated with the help of double time thermodynamic electron and phonon Green’s function theory using a comprehensive Hamiltonian which includes the contribution due to unperturbed electrons and phonons, anharmonic phonons, impurities, and interactions of electrons and phonons. This formulation enables one to resolve the problem of electronic heat transport and equilibrium phenomenon in high-temperature superconductors in an amicable way. The problem of electronic heat capacity and electron-phonon problem has been taken up with special reference to the anharmonicity, defect concentration electron-phonon coupling, and temperature dependence.

The paper presents the results of a study of the temperature dependence of molar heat capacity at constant pressure in the range (from 5 to 300 K) for vanadium-based materials. For all the studied materials, the values of the density of States near the Fermi level are calculated. It was found that for V3Si and V3Ge materials, the values of the state density μ( E ) correlate with the transition temperatures to the superconducting state. For materials V2O3 and V1.973Me0.027O3 (Me - Al, Fe, Cr), it was found that the temperatures of metal-dielectric phase transitions decrease with increasing values of the density of States.
