Real-time trajectory control on a deterministic ion source
C. Lopez, A. Trimeche, D. Comparat +1
The major challenge to improve deterministic single ion sources is to control the position and momentum of each ion. Based on the extra information given by the electron created in…
Laser stimulated deexcitation of Rydberg antihydrogen atoms
Daniel Comparat, Chloé Malbrunot
Antihydrogen atoms are routinely formed at CERN in a broad range of Rydberg states. Ground-state anti-atoms, those useful for precision measurements, are eventually produced throug…
Velocity selected production of metastable positronium
C. Amsler, M. Antonello, A. Belov +52
Positronium in the metastable state exhibits a low electrical polarizability and a long lifetime (1140 ns) making it a promising candidate for interferometry experiments wit…
Phase space density limitation in laser cooling without spontaneous emission
Thierry Chanelière, Daniel Comparat, Hans Lignier
We study the possibility to enhance the phase space density of non-interacting particles submitted to a classical laser field without spontaneous emission. We clearly state that, w…
Producing long-lived Ps via laser excitation in magnetic and electric fields
S. Aghion, C. Amsler, M. Antonello +62
Producing positronium (Ps) in the metastable state is of interest for various applications in fundamental physics. We report here about an experiment in which Ps atom…
