A Boson-Fermion theory that goes beyond the BCS approximations for superconductors
I. Chávez, P. Salas, M. A. Solís +1
A detailed analysis is given of the effects of common and recurring approximations used in conventional superconductivity theories on the condensation energy values, whose magnitud…

Influence of the temperature dependent chemical potential on the condensation energy from a ternary Boson-Fermion model of superconductivity is reported, it consist of unbound elec…
BCS-BEC model of high-Tc superconductivity in layered cuprates with unconventional pairing
