28. Rydberg positronium for tests of antimatter gravity

Dr Stephen Hogan (University College London)

Invited Talk

In its triplet ground state the positronium (Ps) atom self-annihilates on a timescale of 142 ns [1]. This short lifetime rules out the possibility of performing tests of antimatter gravity using ground state Ps atoms. However, when excited to Rydberg states with high principal quantum number [2], direct self-annihilation can become negligible and the Ps lifetime is dominated by radiative...

30. Accelerating positronium using pulsed travelling optical lattices

Invited Talk

The creation of tunable beams of positronium atoms using the optical dipole force from short, pulsed accelerating optical lattices has been studied. Using the favourable polarizability-to-mass ratio of positronium we show that accelerations in excess of 1014g are possible. Simulations have been performed for several cases in which lattice beams capture a significant fraction of ground state...

15. On the use of Atom Optical Tools for Antimatter Experiments

Philippe Braunig (Ruprecht-Karls-Universitaet Heidelberg (DE))

Invited Talk

The field of atom optics has seen tremendous development during the past decades. Tools and methods from this field have evolved from proof-of-principle experiments to reliable instruments with unprecedented precision and are now utilized to tackle fundamental questions – also in different fields of physics. The AEgIS collaboration has used such a tool known as moiré deflectometer, an...
