Bell inequality violation with momentum-entangled massive particles
Y. S. Athreya, S. Kannan, X. T. Yan +3
Bell's theorem revealed the fundamental incompatibility between the predictions of quantum mechanics and local realism. Bell inequality violations have since demonstrated quantum n…
A framework for separating dephasing from decoherence in matter-wave Bell interferometers
S. Kannan, Y. S. Athreya, X. T. Yan +2
Matter-wave Bell interferometers provide a sensitive probe of mass-dependent decoherence in entangled quantum systems. The degree of entanglement is obtained from the Bell-correlat…
Bell correlations between momentum-entangled pairs of atoms
Y. S. Athreya, S. Kannan, X. T. Yan +4
Nonlocal entanglement between pair-correlated particles is a highly counter-intuitive aspect of quantum mechanics, where measurement on one particle can instantly affect the other,…
Measurement of the -wave scattering length between metastable helium isotopes
S. Kannan, Y. S. Athreya, A. H. Abbas +3
We report the first experimental determination of the interspecies -wave scattering length\,() between the state of He and the $2\,^3…
-body anti-bunching in a degenerate Fermi gas of He* atoms
Kieran F. Thomas, Shijie Li, A. H. Abbas +2
A key observable in investigations into quantum systems are the -body correlation functions, which provide a powerful tool for experimentally determining coherence and directly…
Production of a highly degenerate Fermi gas of metastable helium-3 atoms
Kieran F. Thomas, Zhuoxian Ou, Bryce M. Henson +3
We report on the achievement of quantum degeneracy in both components of a Bose-Fermi mixture of metastable helium atoms, He* and He*. Degeneracy is achieved via Doppler co…
