|abstract ;;Quote: derive standard results of electromagnetic theory from macroscopic quantum systems; without Maxwell's equations, traditional quantum formalisms, or correspondence limits|
|30 ;;Quote: superconductors provide direct access to the quantum nature of matter|
|30+;;Quote: a superconductor is in a coherent state of the collective interaction of free electrons; each electron depends on the states of the entire ensemble |
|30+;;Quote: with superconductors, understand quantum effects via waves|
|31 ;;Quote: use a loop for superconductor model of quantum effects; ends are either shorted or insolated; persistent current if shorted|
|33 ;;Quote: quantization occurs because the phase must match at both ends of a closed, superconducting loop|
|36 ;;Quote: the vector potential of quantum mechanics is a bookkeeping device to evaluate the effect of all currents on a point
