Guide to the ACME EDM Experiment

An ongoing series in which I introduce the electron EDM experiment I am working on at Harvard bit by bit, trying as much as possible to avoid technical jargon and making an explanation understandable by a general audience with only high school-level mathematics.

    • Introduction The gist of what we are doing in ACME by measuring the roundness of the electron.
    • A Simple Overview Overall rundown of the entire experiment. Includes an explanation for spin precession, the core physical process which allows us to probe the effects of the deformation of the electron.
    • Atomic Structure A tutorial on how energy is “stored” in atoms and molecules. This is the energy we measure carefully when doing the spin precession.
    • Differential Measurements to the Extreme The concept of a differential measurement, which defines the fundamental operation of the ACME experiment.
