    The Specific Heat Of Boson-Fermion Pair Condensate In Optimally-Doped Cuprates
    (Journal of Multidisciplinary Engineering Science and Technology (JMEST), 2021-12) Mukubwa, A.; Makokha, J. W.; Masinde, F. W.
    Recent studies have shown that the interaction between a finite momentum Cooper-pair boson and a fermion supports superconductivity in cuprates. Specifically, the occurrence of a superconducting energy gap in cuprates is defined by the collective excitation of boson-fermion pair condensates (BFPC) above the ground state. The ground state energy of BFPC in these materials show dependence on single-fermion spins. We study the specific heat of a BFPC in high temperature cuprates based on the ground state energy which represents the total internal energy of the system. The model results are in close proximity with the empirical findings. For instance, the specific heat of the model in Y123 is determined as 𝟏𝟏𝟖.𝟗 𝐉𝐦𝐨𝐥−𝟏𝐊−𝟏, which close to the measured value of 𝟏𝟐𝟕.𝟖 𝐉𝐦𝐨𝐥−𝟏𝐊−𝟏.
