This article reports that the electric drive for the new DD(X) destroyers of the U.S. Navy has sparked competition over exotic motors. One of the keys to success in the U.S. Navy's pursuit of an integrated power system, or electric drive, for its future surface combatants is development of an electric motor that packs much more power in a much smaller machine than has ever gone to sea. The motor the Navy selects to drive its new DD(X) destroyers also could possibly be used in future naval and commercial vessels. That potentially lucrative market has triggered a spirited competition among a number of firms. American Superconductor is working to produce a 36-megawatt motor using high-temperature superconducting technology.

    The nature and behaviour of electronic states in high-temperature superconductors are the centre of much debate. The pseudogap state, observed above the superconducting transition temperature, Tc, is seen by some as a precursor to the superconducting state. Others view it as a competing phase....

    The pseudogap is one of the most pervasive phenomena of high-temperature superconductors. It is attributed either to incoherent Cooper pairing setting in above the superconducting transition temperature, Tc, or to a hidden order parameter competing with superconductivity. Here, we use inelastic...
