A pair potential supporting a mixed mean – field / BCS – phase
We construct a Hamiltonian which in a scaling limit becomes equivalent to one that can be diagonalized by a Bogoliubov transformation. There may appear simultaneously a mean-field and a superconducting phase. They influence each other in a complicated way. For instance, an attractive mean field may stimulate the superconducting phase and a repulsive one may destroy it.
متن کاملUnderstanding BCS Theory
New calculation reveals that E is constant in a thin layer across the Fermi surface, befitting the definition of energy gap parameter, ∆ varies dramatically. The BCS self-consistent equation has a simple and exact solution, showing that the well-known ratio 3.5 must be replaced by 4. A simple formula is found to estimate energy gap from first principles with reasonable accuracy, useful to the c...
متن کاملVortex Dynamics within the BCS Theory
Based on the BCS theory we outline a conventional path integral derivation of the transverse force and the friction for a vortex in a superconductor. The derivation is valid in both clean and dirty limits at both zero and finite temperatures. The transverse force is found to be precisely as what has been obtained by Ao and Thouless using the Berry’s phase method. The friction is essentially the...
متن کاملMathematical Analysis of the BCS-Bogoliubov Theory
Superconductivity is one of the historical landmarks in condensed matter physics. Since Onnes found out the fact that the electrical resistivity of mercury drops to zero below the temperature 4.2K in 1911, the zero electrical resistivity is observed in many metals and alloys. Such a phenomenon is called superconductivity, and the magnetic properties of superconductors as well as their electric ...
متن کاملChern-Simons theory and BCS superconductivity
We study the relationship between the holomorphic unitary connection of ChernSimons theory with temporal Wilson lines and the Richardson’s exact solution of the reduced BCS Hamiltonian. We derive the integrals of motion of the BCS model, their eigenvalues and eigenvectors as a limiting case of the Chern-Simons theory.
