“…We remark in passing that in the nonrelativistic limit β → 0, γ → 1 the háček coefficients (54) reduce to combinations of the standard cartesian tilde coefficients [5], yielding the correspondences b opportunity to sharpen the values in Table IX by about a factor of five. The energy dependence of the amplitudes (52) suggests that the Fermilab and J-PARC experiments will achieve approximately the same sidereal reach to the spherical coefficients with d ¼ 3, with the latter's sensitivity for d ≥ 4 suppressed by a factor of about 10 d−3 . However, the J-PARC experiment enjoys an additional improvement of a factor of about 10 in the sensitivity to certain coefficients that are accompanied by factors of 1=γ, such as b J in Eq.…”

The prospects are explored for testing Lorentz and CPT symmetry in the muon sector via the spectroscopy of muonium and various muonic atoms, and via measurements of the anomalous magnetic moments of the muon and antimuon. The effects of Lorentz-violating operators of both renormalizable and nonrenormalizable dimensions are included. We derive observable signals, extract first constraints from existing data on a variety of coefficients for Lorentz and CPT violation, and estimate sensitivities attainable in forthcoming experiments. The potential of Lorentz violation to resolve the proton radius puzzle and the muon anomaly discrepancy is discussed.

“…The resulting bound on the equatorial componentsb n X andb n Y is at the level of 10 −31 GeV [26]. Recently, this group has placed the first limits on boost effects in the neutron sector of the SME [27]. This type of signal indicates Lorentz violation under boost transformations, and is suppressed by the ratio β ⊕ = v ⊕ /c = 9.9 × 10 −5 of the laboratory speed in the standard Sun frame relative to that of light.…”

Atomic physics can probe the Lorentz and CPT symmetries at the Planck level. Bounds on coefficients for Lorentz violation have been found using atomic clocks, masers, electromagnetic cavities, and Penning traps, among others, and in future it may be possible to place bounds using spectroscopy of antihydrogen atoms. The CPT '04 Meeting on CPT and Lorentz Symmetry was held in August 2004 in Bloomington, Indiana, USA, and covered Lorentz violation in all branches of physics. This report gives an overview of the recent advances in Lorentz-symmetry studies in atomic and optical physics. * Conference report, at invitation of Comments on Atomic, Molecular, and Optical Physics (CAMOP), on CPT '04, Third Meeting on CPT and Lorentz Symmetry,

“…Comagnetometry experiments also utilize two atomic species sharing the same volume. One such apparatus was used to create a highly accurate nuclear spin gyroscope [9], while other groups have used comagnetometers in searches for physics beyond the standard model, such as setting upper bounds on P,T-violating permanent electric dipole moment [10] as well as bounds on Lorentz and CPT violation [11].…”

Possibility of Stark-insensitive cotrapping of two atomic species in optical lattices

2011

Much effort has been devoted to removing differential Stark shifts for atoms trapped in specially tailored "magic" optical lattices, but thus far work has focused on a single trapped atomic species. In this work, we extend these ideas to include two atomic species sharing the same optical lattice. We show qualitatively that, in particular, scalar J = 0 divalent atoms paired with non-scalar state atoms have the necessary characteristics to achieve such Stark shift cancellation. We then present numerical results on "magic" trapping conditions for 27 Al paired with 87 Sr, as well as several other divalent atoms.
