BCS ansatz for superconductivity in the canonical ensemble and the Pauli exclusion principle
G. Zhu, M. Combescot, O. Betbeder-Matibet
The usual formulation of the BCS ansatz for superconductivity in the grand canonical ensemble makes the handling of the Pauli exclusion principle between paired electrons straightf…
Energy of N Cooper pair by analytically solving Richardson-Gaudin equations
Michel Crouzeix, Monique Combescot
This Letter provides the solution to a yet unsolved basic problem of Solid State Physics: the ground state energy of an arbitrary number of Cooper pairs interacting via the Bardeen…
Competition between BCS-pairing and "moth-eaten effect" in BEC-BCS crossover
Guojun Zhu, Monique Combescot
We study the change in condensation energy from a single pair of fermionic atoms to a large number of pairs interacting via the reduced BCS potential. We find that the energy-savin…
BCS ansatz, Bogoliubov approach to superconductivity and Richardson-Gaudin exact wave function
M. Combescot, W. V. Pogosov, O. Betbeder-Matibet
The Bogoliubov approach to superconductivity provides a strong mathematical support to the wave function ansatz proposed by Bardeen, Cooper and Schrieffer (BCS). Indeed, this ansat…
From one to Cooper pairs, step by step
W. V. Pogosov, M. Combescot
We extend the one-pair Cooper configuration towards Bardeen-Cooper-Schrieffer (BCS) model of superconductivity by adding one-by-one electron pairs to an energy layer where a small…
