This Week in Physics from APS

    "This Week in Physics" from APS

    Below are some abstracts from "This Week in Physics" — February 2, 2009. This newsletter has been published recently by the American Physical Society. Membership may be required to receive this electronic weekly.

    Its articles represent cutting edge, far reaching yet simply based experimental and theoretical works. They read like a prescient condensation of heftier journals. I find TWIP readable and elegant.

    Do any of you subscribe to it? How does it impress you?

    Viewpoint: Debating the source of a rare particle
    Simon Swordy, Physics 2, 10 (2009) – Published February 2, 2009

    Many cosmologists believe that antiprotons in cosmic rays come from the annihilation of dark matter. Data from the PAMELA experiment on board a Russian satellite provide an important test of this possibility.

    Viewpoint: How the tail wags the dog in ultracold atomic gases
    Eric Braaten, Physics 2, 9 (2009) – Published February 2, 2009

    Recent calculations of the properties of ultracold atoms have revealed how two-body interactions at very short distances determine essential properties of many-body systems.

    Synopsis: The chill factor of squeezed light
    Published February 2, 2009

    A laser beam in a squeezed state may be an effective source for cooling a macroscopic resonator.

    Synopsis: Relaxing the requirements for scalable quantum computing
    Published February 2, 2009

    A rigorous estimate shows that an error correction code for a scalable quantum computer can accommodate error at the 0.1% level—about ten times more tolerant than most other methods.

    Synopsis: Superconductivity can be sensitive
    Published February 2, 2009

    Small changes in stoichiometry can destroy superconductivity in FeSe.

    Synopsis: Cooling with magnets
    Published January 28, 2009

    Scientists identify the microscopic origin of a record magnetocaloric effect in Mn1+yFe1-y(P1-xGex)
