van der Waals coefficients for positronium interactions with atoms
A. R. Swann, J. A. Ludlow, G. F. Gribakin
The random-phase approximation with exchange (RPAE) is used with a -spline basis to compute dynamic dipole polarizabilities of noble-gas atoms and several other closed-shell ato…
Investigating the static dipole polarisability of noble gas atoms confined in impenetrable spheres and shells
J. A. Ludlow, Teck-Ghee Lee
The static dipole polarisability of noble gas atoms confined by impenetrable spheres and spherical shells is studied using the B-spline random phase with exchange approximation. Th…
Positron scattering and annihilation on noble gas atoms
D. G. Green, J. A. Ludlow, G. F. Gribakin
Positron scattering and annihilation on noble gas atoms below the positronium formation threshold is studied ab initio using many-body theory methods. The many-body theory provides…
Investigating the nuclear Schiff moment of Pb in ferroelectric PbTiO
J. A. Ludlow, O. P. Sushkov
A positive experimental measurement of the nuclear Schiff moment would have important implications for physics beyond the standard model. To aid in the interpretation of a proposed…
A large-scale R-matrix calculation for electron-impact excitation of the Ne O-like ion
B. M. McLaughlin, Teck-Ghee Lee, J. A. Ludlow +4
The five J levels within a or ground state complex provide an excellent testing ground for the comparison of theoretical line ratios with astrophysically observed…
Many-body theory calculations of positron binding to negative ions
J. A. Ludlow, G. F. Gribakin
A many-body theory approach developed by the authors [Phys. Rev. A 70, 032720 (2004)] is applied to positron bound states and annihilation rates in atomic systems. Within the forma…
