  • Statistical processing techniques make it possible to extract features of a cold atom cloud from images taken of a BEC experiment.
    The Anderson and Cornell groups have adapted two statistical techniques used in astronomical data processing to the analysis of images of ultracold atom gases. Image analysis is necessary for obtaining quantitative information about the behavior of an ultracold gas under different experimental conditions. Until now, the preferred method has been to find a shape (such as a Gaussian) that looks like the results and write an image-fitting routine to probe a series of photographs. The drawback is that information extracted this way will be biased by the model chosen.
  • Symbol of electronic transistor
    JILA Fellow Dana Z. Anderson, JILA visiting scientist Alex Zozulya, and a colleague from the Worcester Polytechnic Institute postulate that the ultracold coherent atoms in a Bose-Einstein Condensate (BEC) could be configured to act like electrons in a transistor. An 鈥渁tom transistor鈥 would exhibit absolute and differential gain, as well as allow for the movement of single atoms to be resolved in a precision scientific measurement.
