Journal ArticleDOI
Geonium theory: Physics of a single electron or ion in a Penning trap
Lowell S. Brown,Gerald Gabrielse +1 more
TL;DR: In this paper, the theory of a single charged particle in a Penning trap is reviewed, beginning with simple first-order orbits and progressively dealing with small corrections which must be considered owing to the experimental precision that is being achieved.
Journal ArticleDOI
Order of Magnitude Smaller Limit on the Electric Dipole Moment of the Electron
Jacob Baron,Wesley C. Campbell,David DeMille,John M. Doyle,Gerald Gabrielse,Yulia V. Gurevich,Paul Hess,Nicholas R. Hutzler,Emil Kirilov,Ivan Kozyryev,Brendon O'Leary,Cristian Panda,Maxwell Parsons,Elizabeth Petrik,Ben Spaun,Amar C. Vutha,Adam West +16 more
TL;DR: Spin precession measurements in the polar molecule thorium monoxide indicate a nearly spherical charge distribution of an electron, which constrains T-violating physics at the TeV energy scale.
Journal ArticleDOI
New Measurement of the Electron Magnetic Moment and the Fine Structure Constant
TL;DR: A measurement using a one-electron quantum cyclotron gave the electron magnetic moment in Bohr magnetons, g/2=1.001 159 652 180 73 (28) [0.28 ppt], with an uncertainty 2.7 and 15 times smaller than for previous measurements in 2006 and 1987.
New measurement of the electron magnetic moment and the fine structure constant
TL;DR: The new measurement has an uncertainty that is about six times smaller, and it shifts the values by 1.7 standard deviations, so the lowest quantum levels of the spin and cyclotron motion are resolved, and the cycle frequencies as well as spin frequencies are determined using quantum jump spectroscopy.
Journal ArticleDOI
Background-free observation of cold antihydrogen with field-ionization analysis of its states.

TL;DR: A background-free observation of cold antihydrogen atoms is made using field ionization followed by antiproton storage, a detection method that provides the first experimental information aboutAntihydrogen atomic states, suggesting that the antiHydrogen is formed via three-body recombination.
