Long-range atom-surface interactions for cold atoms
James F. Babb
Studies of the long-range interactions between cold atoms and surfaces are now of vital interest. The interest is partly driven by nanotechnology applications, partly by the explod…
Theoretical Study of Pressure Broadening of Lithium Resonance Lines by Helium Atoms
Cheng Zhu, James F. Babb, Alex Dalgarno
Quantum mechanical calculations are performed of the emission and absorption profiles of the lithium 2s-2p resonance line under the influence of a helium perturbing gas. We use car…
High-precision calculations of van der Waals coefficients for heteronuclear alkali-metal dimers
A. Derevianko, J. F. Babb, A. Dalgarno
Van der Waals coefficients for the heteronuclear alkali-metal dimers of Li, Na, K, Rb, Cs, and Fr are calculated using relativistic ab initio methods augmented by high-precision ex…
Ultracold collisions of metastable helium atoms
P. J. Leo, V. Venturi, I. B. Whittingham +1
We report scattering lengths for the singlet Sigma g +, triplet Sigma u + and quintet Sigma g + adiabatic molecular potentials relevant to collisions of two metastable (n=2 triplet…
Theoretical study of the absorption spectra of the sodium dimer
H. -K. Chung, K. Kirby, J. F. Babb
Absorption of radiation from the sodium dimer molecular states correlating to Na(3s)-Na(3s) is investigated theoretically. Vibrational bound and continuum transitions from the sing…
The dipole polarizability of the hydrogen molecular ion
J. M. Taylor, A. Dalgarno, J. F. Babb
A procedure is described for the precise nonrelativistic evaluation of the dipole polarizabilities of H_2^+ and D_2^+ that avoids any approximation based on the size of the electro…
