Cambridge Scientists Create Huge Quantum Particles 52

judgecorp writes "Researchers at Cambridge University have produced a quantum fluid thousands of times larger than previously, leading to the possibility of polaritons produced at lower power and at a broader temperature range. This could lead to quantum circuits, as well as applications such as more sensitive gyroscopes." The paper was published in Nature Physics on January 8th, but a pre-press version is available through arXiv.

    Quantum linguistics?

    or are they past?

    Stop adjectivizing quantum verbs, they don't like it.

    and if it is dangling participle, it will be smaller

    When I read the title, this scenario immediately popped into my head:

    Physicist A: "We need to make something cool out of them... like one of those tiny violins or the art on a microchip..."
    Physicist B: "Let's make boobs! Every sculptor makes boobs eventually! Quantum boobs!"
    Physicist A: "OK, but they gotta be HUGE! Then we can use normal particles for the nipples!"

    This could lead to quantum circuits

    Great! My lights have been needing a bottle of blinker fluid for the longest time!

  • I don't understand what's new about polaritons in semiconductor nanostructures. You only need a multi quantum well structure and pump it at the right angle with a laser.

    Um... TFA says "larger than usual". Not "larger than before".

    I think the record still belongs to Bose condensates [] that have been created in the lab, essentially amounting to huge single quantum "particles".
  • The SEP field.
  • I know the menagerie of particles and things-we-like-to-model-as-if-they-were-particles becomes huge.

    Even so, after starting my morning with an article about quantum "polaritons", I will have this [] running through my head all day...
    Lyrics here [] if you don't want your friends to know you listen to goth trek filk.

    • If it helps Polaritons don't belong in the standard model megagerie. They are quasi-particles. Collective states can (often) be modelled as a system with the number of quasi-particles representing the excitation of the system, if these quasi-particles have well defined properties, act at point, commute with other useful observable then its a useful description of reality, but its still just electrons and nucleii as usual. Quasi-particles are very useful at reducing complex system to simple ones in condensed
  • they follow you home.

    As long as they don't hog the sofa!

  • They either created quantum particles or they didn't. I'm going to check, and I'm sure they didn't. Sure enough.
