Heteronuclear ionizing collisions between laser-cooled metastable helium atoms
J. M. McNamara, R. J. W. Stas, W. Hogervorst +1
We have investigated cold ionizing heteronuclear collisions in dilute mixtures of metastable (2 3S1) 3He and 4He atoms, extending our previous work on the analogous homonuclear col…
Camparison of the Hanbury Brown-Twiss effect for bosons and fermions
Tom Jeltes, John M. McNamara, Wim Hogervorst +8
Fifty years ago, Hanbury Brown and Twiss (HBT) discovered photon bunching in light emitted by a chaotic source, highlighting the importance of two-photon correlations and stimulati…
Production of a degenerate Fermi gas of metastable helium-3 atoms
W. Vassen, T. Jeltes, J. M. McNamara +1
We give an overview of the experiments at the Laser Centre of the Vrije Universiteit in Amsterdam on ultracold gases of metastable helium-4 and helium-3 as well as mixtures of both…
Producing and Detecting Correlated atoms
Christoph I. Westbrook, Martijn Schellekens, Aurélien Perrin +12
We discuss experiments to produce and detect atom correlations in a degenerate or nearly degenerate gas of neutral atoms. First we treat the atomic analog of the celebrated Hanbury…
A Degenerate Bose-Fermi Mixture of Metastable Atoms
J. M. McNamara, T. Jeltes, A. S. Tychkov +2
We report the observation of simultaneous quantum degeneracy in a dilute gaseous Bose-Fermi mixture of metastable atoms. Sympathetic cooling of helium-3 (fermion) by helium-4 (boso…
Homonuclear ionizing collisions of laser-cooled metastable helium atoms
R. J. W. Stas, J. M. McNamara, W. Hogervorst +1
We present a theoretical and experimental investigation of homonuclear ionizing collisions of laser-cooled metastable helium atoms, considering both the fermionic He-3 and bosonic…
