    "abstract": "As a consequence of the Aharonov-Bohm effect, there is a quantum-induced\nattraction between a charged particle and a rigid, impenetrable hoop made from\nan arbitrarily thin tube containing a superconductor quantum of magnetic flux.\nThis is remarkable because in classical physics there is no force between the\ntwo objects, and quantum-mechanical effects (associated with uncertainty\nprinciple energy) generally are repulsive rather than attractive. For an\nincident spinless charged particle in a P wave (in a configuration with total\nangular momentum zero) we verify a resonance just above threshold using the\nKohn variational principle in its S-matrix form. Even if optimistic choices of\nparameters describing a model system with these properties turned out to be\nfeasible, the temperature required to observe the resonance would be far lower\nthan has yet been attained in the laboratory.",
