Coherence Factors Beyond the BCS Result
Gregory Gorohovsky, Eldad Bettelheim
The dynamics of BCS (Bardeen-Cooper-Schrieffer) superconductors is fairly well understood due to the availability of a mean field solution for the pairing Hamiltonian, a solution w…

Exact expectation values within Richardson's approach for the pairing Hamiltonian in a macroscopic system
Gregory Gorohovsky, Eldad Bettelheim
BCS superconductivity is explained by a simple Hamiltonian describing an attractive pairing interaction between pairs of electrons. The Hamiltonian may be treated using a mean-fiel…
