The application of the fractional exclusion statistics to the BCS theory--a redefinition of the quasiparticle energies

Dragos-Victor Anghel, George Alexandru Nemnes

The effective energy of a superconductor $E_{e f f} (T)$ at temperature $T$ is defined as the difference between the total energy at temperature $T$ and the total energy at 0~K. We ca…
