Superconductor Research Points To New Phase of Matter 59

unil_1005 writes "Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this 'pseudogap' has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature. 'Our findings point to management and control of this other phase as the correct path toward optimizing these novel superconductors for energy applications, as well as searching for new superconductors,' said Zhi-Xun Shen of the Stanford Institute for Materials and Energy Science."

    It don't matter to me.

      You obviously have no idea what the implications of a finding a room temperature super-conductor are they're actually very exciting and at the very lest not boring. It would push most of our technology forward at least 20 years if we can find a way to mass produce one. Since you obviously use technology it defiantly does matter to you.

        That's not gas whooshing over your head.
    • Your post made me laugh. The replies made me sad, knowing that Sheldon Cooper is alive and well.

    • There are lots and lots of phases of matter, the 3 (or maybe 4 depending on your teacher) that you learned about in elementary science classes are just the most common.

        They're the only phases that matter.

        just to name the ones i've heard of (through being nothing more than someone who pays attention but without any real interest)

        solid
        liquid crystal (yes like in watch displays)
        liquid
        gas
        plasma

        aside from the liquid crystal (it's a different phase or some such cos it's not the space between the molecules but rather the alignment of the molecules which determine if it's currently solid or liquid) i always liked how science has basically said the world is made of four things; earth, water, air and fire...

          A zero-friction liquid is a superfluid, not a Bose-Einstein condensate. Both superfluids and BEC are distinct phases of matter, though. Simply sharing some properties with another phase is insufficient -- otherwise liquid and gas wouldn't be distinct phases.

    I thought plasma, bose-einsten condensate and quark-gluon plasmas were all recognised as seperate states of matter?

    • That's why no one described it as the "4th" phase of matter. Just a new phase.

      Plasma is the fourth "common" phase of matter.

      Bose-Einstein condensates and other novel phase are also phases, but aren't exhibited in all materials.

      For that matter, most solids, particularly crystalline solids, have many different phases that correspond to different crystalline structures.

      Also, "liquid" and "gas" aren't always distinct phases.

      • Off the top of my head:
        Solid
        Liquid
        Critical state
        Supercritical matter
        Gas
        Plasma
        Liquid crystal
        Glass
        Bose-Einstein condensate
        Fermionic condensate
        Rydberg molecule
        Superfluid
        Quark-Gluon plasma

        Probably a few others. And now pseudogap.

      On this pathetic plane, perhaps. Others [scribd.com] may have found different metaphors [blogspot.com].
    • There are also liquid crystal phases. Basically, ordered liquids.

  • Aren't there, like, 14 now?

  • We're going to spend all this time and effort to create room temperature super conductors only to have a bunch of three-legged two-headed aliens develop a bacteria to eat it and make our cities fall.
