Abstract
There are two categories of superconductors; s-wave superconductors that are isotropic and d-wave superconductors that are anisotropic. The microscopic theory of superconductivity by Bardeen, Schrieffer and Cooper (BCS theory) explains s-wave pairing of charges under ambient pressure but it fails to explain charge pairing under high pressure. Studies have shown that superconductivity in hydrides is due to electron-phonon mediation. Models have been developed to explain the pressure effect on Tc but so far no unified model has been agreed upon to explain HTSC under pressure using the Bogoliubov-Valatin Transformation (BVT) formalism. The developed theory was used in this work to give more understanding of the superconducting process under pressure and carry on a comparison with other researchers. The systems energy, specific heats, entropy and Sommerfield coefficient were determined. The specific heat capacity for LaH10 is 0.0315meV/K at Tc=237.9 and 210GPa. The systems have maximum Cv =4.68meV/K at T=6K. LaH10 shows Sommerfield coefficient of 0.00235meV/K2 at the same stated pressure values. The value of entropy for the hydride at Tc is 0.13meV/K2 for LaH10. The highest entropy for LaH10 is 0.451meV/K2 occurs at 1000K.
