摘要：
A generalization of the BCS ground state is suggested and leads to expectation values for the energy and the current density consistent with the Ginzburg-Landau expressions. PSI(R) describes the quantum-mechanical motion of the center of mass of the superconducting pairs, and PSI*(R)PSI(R) turns out to give the number of superconducting pairs per unit volume at R. Extension to finite temperatures appears to be a possibility.
