    Description: The discovery of an electric dipole moment (EDM) of a fundamental particle would provide evidence for physics beyond the Standard Model. Many popular extensions to the Standard Model, such as supersymmetry, predict electron electric dipole moments (eEDMs) within a few orders of magnitude of the current experimental limit. The PbO* experiment uses several unique characteristics of the diatomic molecule lead oxide, that make it a particularly sensitive probe for detecting an eEDM. The valence electrons in PbO experience an effective intramolecular electric field of > 1010 V cm −1 which greatly enhances the energy shift due to an eEDM. Because PbO is chemically stable, unlike many other molecules used in EDM searches, it can be used in a high temperature vapor cell. The large densities in the vapor cell give the PbO* experiment a high statistical sensitivity. In this thesis we will discuss improvements to both the apparatus and the experimental methods that have increased the statistical sensitivity...

    Titre: Towards an improved test of Bose-Einstein statistics for photons
    Auteur: Brown, Damon; Budker, Dmitry; Demille, David P.
    Description: In this contribution we describe our current efforts at Berkeley to improve upon a limit on Bose-Einstein statistics violation for photons obtained earlier (D. P. DeMille, D. Budker, N. Derr, and E. Deveney, Phys. Rev. Lett. 83 (20), 1378 (1999)). The principle differences between the new and the previous experiments are the use of a narrow-band cw laser, an atomic beam, a different transition in atomic Ba, and possibly a different detection technique. We also discuss the ultimate limits that one can hope to obtain with this degenerate two-photon transition technique. Some potential conceptual difficulties with the interpretation of this experiment and the ways to avoid them are discussed as well.

    Titre: The electric dipole moment of the electron: An intuitive explanation for the evasion of Schiff’s theorem
    Auteur: Commins, Eugene D.; Jackson, J. D.; Demille, David P.
    Sujet: Papers
    Description: In most experimental searches for the electron electric dipole moment, one searches for a linear Stark effect in a paramagnetic atom or molecule and interprets the result in terms of the electric dipole moment of the unpaired valence electron(s). Schiff’s theorem states that in the limit of nonrelativistic quantum mechanics, there can be no linear Stark effect to first order in the electric dipole moment. Sandars has shown that Schiff’s theorem is not applicable when special relativity is taken into account. We give a heuristic explanation for this relativistic effect, which corrects a widespread misconception in the literature.
