The Bogoliubov equations and their application to a normal-superconducting boundary
The Bogo1iubov equations are used to investigate the pair potential and the electronic excitations associated with a norma1- superconducting boundary in an extreme type I superconductor, The method of the Bogoliubov equations has three advantages, for this calculation, over other methods: (1) the …

Generalization of the BTK Theory to the Case of Finite Quasiparticle Lifetimes
… inserted into the strong coupling version of the Bogoliubov equations and subsequently, the coherence factors are computed. By applying the suitable boundary conditions to the case of a normal-superconducting interface, the probability current densities for the Andreev reflection, the normal …

Current flow in inhomogeneous superconductors
… We examine approximate solutions to the Bogoliubov equations in the limits that the pair potential, ~('f), varies quickly or slowly compared to a coherence length, ~ (T), to see how well such solutions conserve charge c flux. These solutions are then used to compute the linear current …
