Spontaneous quantum phase slips by 2π in thin superconducting wires could cause errors in superconducting computers. The rate of such phase slips at T«T[sub c] is estimated, and shown to be very small as long as the wire is >20 nm in diameter. © 2002 American Institute of Physics.

    The electronic structure of simple crystalline solids can be completely described in terms either of local quantum states in real space (r-space), or of wave-like states defined in momentum-space (k-space). However, in the copper oxide superconductors, neither of these descriptions alone may be...
