...course of his research at CfA, Ronald L. Walsworth and his team have developed a xenon gas laser polarization technique that may enhance the capabilities...
Building on a theory by Soviet physicist Andrei Sakharov, Walsworth, physicist Eduardo R. Oteiza and co-workers have been working on detecting an electric dipole of xenon to gain insight into the laws governing the formation of the universe...
...recent Smithsonian Institution Research Reports, Walsworth explained how difficult it was to detect the dipole, saying that if one were to blow up an the size of the Earth, the xenon dipole wouldamount to less than the width of a human hair...
...very short distances, electrons can traverse the gap between the tip and the surface, a phenomenon known as tunneling. This generates a tiny current that can be used to move atoms and molecules around with pinpoint precision. Thus last year physicists from IBM's Almaden Research Center manipulated 35 xenon atoms on a nickel surface to spell out their company's logo. They have also fashioned seven atoms into a minuscule beaker in which they can observe chemical reactions at an atomic level, and they devised a working version of a single-atom electronic switch that, in theory, could replace...
Smallest Advertisement Using a powerful microscope, IBM researchers lined up individual xenon atoms to spell out the company's initials. That clever display of know-how got magnified pictures of the minuscule logo into newspapers all over the world -- for free...
