✦ Synopsis

The Aharanov-Bohm effect is the influence of classically inaccessible electromagnetic fields on quantum wave functions. In this paper we consider the Ginsburg-Landau (GL) equations for the stationary states of a thin, superconducting cylinder in the presence of a curl-free, static electromagnetic potential corresponding to zero fields. We solve the GL equations explicitly to obtain self-consistent solutions for the current density, the induced field and the free energy in a well-defined and accessible approximation. The analysis makes quantitative predictions which can, in principle, be experimentally tested to provide a clear and convincing demonstration of the Aharanov-Bohm effect.

Using the weak field expansion, we have calculated the groundstate energy of the hydrogen atom in a magnetic field for values of the field up to about 10" G. The perturbative expansion has been summed by an order-dependent mapping method. Results are compared with previous calculations. This method
