High resolution adaptive imaging of a single atom
J. D. Wong-Campos, K. G. Johnson, B. Neyenhuis +2
We report the optical imaging of a single atom with nanometer resolution using an adaptive optical alignment technique that is applicable to general optical microscopy. By decompos…
Photoassociation of spin polarized Chromium
Jahn Rührig, Tobias Bäuerle, Paul S. Julienne +2
We report the homonuclear photoassociation (PA) of ultracold atoms in an optical dipole trap. This constitutes the first measurement of PA in an element with t…
Rashba realization: Raman with RF
Daniel L. Campbell, Ian B. Spielman
We theoretically explore a Rashba spin-orbit coupling scheme which operates entirely in the absolute ground state manifold of an alkali atom, thereby minimizing all inelastic proce…
A development of the CI + all-order method and application to the parity-nonconserving amplitude and other properties of Pb
S. G. Porsev, M. G. Kozlov, M. S. Safronova +1
We have further developed and extended a method for calculation of atomic properties based on a combination of the configuration interaction and coupled-cluster approach. We have a…
Direct observation of Feshbach enhanced -wave scattering of fermions
Dina Genkina, Lauren M. Aycock, Benjamin K. Stuhl +3
We directly measured the normalized -wave scattering cross-section of ultracold atoms across a magnetic-field Feshbach resonance by colliding pairs of degener…
Enhanced Magnetic Trap Loading for Atomic Strontium
D. S. Barker, B. J. Reschovsky, N. C. Pisenti +1
We report on a technique to improve the continuous loading of atomic strontium into a magnetic trap from a Magneto-Optical Trap (MOT). This is achieved by adding a depumping laser…
Actinide ions for testing the spatial variation hypothesis
V. A. Dzuba, M. S. Safronova, U. I. Safronova +1
Testing the spatial variation of fine-structure constant indicated in [Webb et al., Phys. Rev. Lett. 107, 191101 (2011)] with terrestrial laboratory atomic measurements require…
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…
Energy shift due to anisotropic black body radiation
Victor V. Flambaum, Sergey G. Porsev, Marianna S. Safronova
In many applications a source of the black-body radiation (BBR) can be highly anisotropic. This leads to the BBR shift that depends on tensor polarizability and on the projection o…
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…
Photon-correlation measurements of atomic-cloud temperature using an optical nanofiber
J. A. Grover, P. Solano, L. A. Orozco +1
We develop a temperature measurement of an atomic cloud based on the temporal correlations of fluorescence photons evanescently coupled into an optical nanofiber. We measure the te…
High precision measurement of the 87Rb D-line tune-out wavelength
R. H. Leonard, A. J. Fallon, C. A. Sackett +1
We report an experimental measurement of a light wavelength at which the ac electric polarizability equals zero for 87Rb atoms in the F=2 ground hyperfine state. The experiment use…
Degenerate Bose-Fermi mixtures of rubidium and ytterbium
Varun D. Vaidya, J. Tiamsuphat, S. L. Rolston +1
We report the first realization of a quantum degenerate mixture of bosonic Rb and fermionic Yb atoms in a hybrid optical dipole trap with a tunable, species-dependen…
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…
Magic wavelengths for the transition in rubidium
E. A. Goldschmidt, D. G. Norris, S. B. Koller +5
Magic wavelengths, for which there is no differential ac Stark shift for the ground and excited state of the atom, allow trapping of excited Rydberg atoms without broadening the op…
Optical Feshbach resonances: Field-dressed theory and comparison with experiments
T. L. Nicholson, S. Blatt, B. J. Bloom +4
Optical Feshbach resonances (OFRs) have generated significant experimental interest in recent years. These resonances are promising for many-body physics experiments, yet the pract…
