Coherent excitation of a Hz scale optical magnetic quadrupole transition
V. Klüsener, S. Pucher, D. Yankelev +7
We report on the coherent excitation of the ultranarrow - magnetic quadrupole transition in . By confining atoms in a state in…
Effective three particle forces in polyvalent atoms
M. G. Kozlov, M. S. Safronova, S. G. Porsev +1
We study effective three-particle interactions between valence electrons, which are induced by the core polarization. Such interactions are enhanced when valence orbitals have stro…
Towards a Mg lattice clock: Observation of the transition and determination of the magic wavelength
A. P. Kulosa, D. Fim, K. H. Zipfel +9
We optically excite the electronic state in Mg atoms, laser-cooled and trapped in a magic-wavelength lattice. An applied magnetic field enhances the coupling…
Strongly enhanced effects of Lorentz symmetry violation in entangled Yb+ ions
V. A. Dzuba, V. V. Flambaum, M. S. Safronova +4
Lorentz symmetry is one of the cornerstones of modern physics. However, a number of theories aiming at unifying gravity with the other fundamental interactions including string fie…
Observation of an unexpected negative isotope shift in 229Th+ and its theoretical explanation
M. V. Okhapkin, D. M. Meier, E. Peik +3
We have measured the hyperfine structure and isotope shifts of the 402.0 nm and 399.6 nm resonance lines in 229Th+. These transitions could provide pathways towards the 229Th isome…
A Michelson-Morley Test of Lorentz Symmetry for Electrons
T. Pruttivarasin, M. Ramm, S. G. Porsev +4
All evidence so far suggests that the absolute spatial orientation of an experiment never affects its outcome. This is reflected in the Standard Model of physics by requiring all p…
