Effective three-body interactions of neutral bosons in optical lattices
P. R. Johnson, E. Tiesinga, J. V. Porto +1
We show that there are effective three- and higher-body interactions generated by the two-body collisions of atoms confined in the lowest vibrational states of a 3D optical lattice…
Cancellation of the collisional frequency shift in caesium fountain clocks
K. Szymaniec, W. Chalupczak, E. Tiesinga +3
We have observed that the collisional frequency shift in primary caesium fountain clocks varies with the clock state population composition and, in particular, is zero for a given…
Loading Bose condensed atoms into the ground state of an optical lattice
P. S. Julienne, Y. B. Band, C. J. Williams +1
We optimize the turning on of a one-dimensional optical potential, V_L(x,t) = S(t) V_0 cos^2(kx) to obtain the optimal turn-on function S(t) so as to load a Bose-Einstein condensat…
Precise determination of Li cold collision parameters by radio-frequency spectroscopy on weakly bound molecules
M. Bartenstein, A. Altmeyer, S. Riedl +9
We employ radio-frequency spectroscopy on weakly bound Li molecules to precisely determine the molecular binding energies and the energy splittings between molecular states…
Quantum computations with atoms in optical lattices: marker qubits and molecular interactions
T. Calarco, U. Dorner, P. Julienne +2
We develop a scheme for quantum computation with neutral atoms, based on the concept of "marker" atoms, i.e., auxiliary atoms that can be efficiently transported in state-independe…
Quantum Logic for Trapped Atoms via Molecular Hyperfine Interactions
G. K. Brennen, I. H. Deutsch, C. J. Williams
We study the deterministic entanglement of a pair of neutral atoms trapped in an optical lattice by coupling to excited-state molecular hyperfine potentials. Information can be enc…
