Autoionization of spin-polarized metastable helium in tight anisotropic harmonic traps
Timothy J. Beams, Ian B. Whittingham, Gillian Peach
Spin-dipole mediated interactions between tightly confined metastable helium atoms couple the spin-polarized quintet state to the singlet state…
Spin-dipole induced lifetime of the least-bound quintet sigma state of He(2S)+He(2S)
Timothy J. Beams, Gillian Peach, Ian B. Whittingham
The properties of the least-bound vibrational level (v=14) of the quintet sigma state formed during the ultracold collision of two spin-polarized metastable helium atoms are crucia…
Ultracold atomic collisions in tight harmonic traps: Perturbation theory, ionization losses and application to metastable helium atoms
T J Beams, G Peach, I B Whittingham
Collisions between tightly confined atoms can lead to ionization and hence to loss of atoms from the trap. We develop second-order perturbation theory for a tensorial perturbation…
Ultracold collisions in tight harmonic traps: Quantum defect model and application to metastable helium atoms
Gillian Peach, Ian B Whittingham, Timothy J Beams
We analyze a system of two colliding ultracold atoms under strong harmonic confinement from the viewpoint of quantum defect theory and formulate a generalized self-consistent metho…
