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…
A matter wave Rarity-Tapster interferometer to demonstrate non-locality
Kieran F. Thomas, Bryce M. Henson, Yu Wang +4
We present an experimentally viable approach to demonstrating quantum non-locality in a matter wave system via a Rarity-Tapster interferometer using two -wave scattering halos g…
Trap Frequency Measurement with a Pulsed Atom Laser
B. M. Henson, K. F. Thomas, Z. Mehdi +4
We describe a novel method of single-shot trap frequency measurement for a confined Bose-Einstein Condensate, which uses an atom laser to repeatedly sample the mean velocity of tra…
Measurement of a helium tune-out frequency: an independent test of quantum electrodynamics
B. M. Henson, J. A. Ross, K. F. Thomas +9
Despite quantum electrodynamics (QED) being one of the most stringently tested theories underpinning modern physics, recent precision atomic spectroscopy measurements have uncovere…
On the survival of the quantum depletion of a condensate after release from a magnetic trap
J. A. Ross, P. Deuar, D. K. Shin +4
We present observations of the high momentum tail in expanding Bose-Einstein condensates of metastable Helium atoms released from a harmonic trap. The far-field density profile exh…
Frequency measurements of transitions from the state to the , , and states in ultracold helium
Jacob A. Ross, Kieran F. Thomas, Bryce M. Henson +4
We perform laser absorption spectroscopy with ultracold He atoms to measure the energy intervals between the level and five levels in the n = 5 manifold. The lase…
Recreating the OSIRIS-REx Slingshot Manoeuvre from a Network of Ground-Based Sensors
Trent Jansen-Sturgeon, Benjamin A. D. Hartig, Gregory J. Madsen +20
Optical tracking systems typically trade-off between astrometric precision and field-of-view. In this work, we showcase a networked approach to optical tracking using very wide fie…
Entanglement-based 3D magnetic gradiometry with an ultracold atomic scattering halo
D. K. Shin, J. A. Ross, B. M. Henson +2
Ultracold collisions of Bose-Einstein condensates can be used to generate a large number of counterpropagating pairs of entangled atoms, which collectively form a thin spherical sh…
A strong Bell correlation witness between spatially separated pairs of atoms
D. K. Shin, B. M. Henson, S. S. Hodgman +3
The violation of a Bell inequality is a striking demonstration of how quantum mechanics contradicts local realism. Although the original argument was presented with a pair of spin…
Approaching the adiabatic timescale with machine-learning
Bryce M. Henson, Dong K. Shin, Kieran F. Thomas +4
The control and manipulation of quantum systems without excitation is challenging, due to the complexities in fully modeling such systems accurately and the difficulties in control…
Bogoliubov-Cherenkov Radiation in an Atom Laser
B. M. Henson, Xuguang Yue, S. S. Hodgman +5
We develop a simple yet powerful technique to study Bogoliubov-Cherenkov radiation by producing a pulsed atom laser from a strongly confined Bose-Einstein condensate. Such radiatio…
The First Measurement of the Tune-Out Wavelength in He*
B. M. Henson
The workhorse of atomic physics, quantum electrodynamics, is one of the best-tested theories in physics. However recent discrepancies have shed doubt on its accuracy for complex at…
Widely tunable, narrow linewidth external-cavity gain chip laser for spectroscopy between 1.0 - 1.1 um
Dong K. Shin, Bryce M. Henson, Roman I. Khakimov +5
We have developed and characterised a stable, narrow linewidth external-cavity laser (ECL) tunable over 100 nm around 1080 nm, using a single-angled-facet gain chip. We propose the…
Ghost Imaging with Atoms
R. I. Khakimov, B. M. Henson, D. K. Shin +4
Ghost imaging is a technique -- first realized in quantum optics -- in which the image emerges from cross-correlation between particles in two separate beams. One beam passes throu…
Precision Measurement for Metastable Helium Atoms of the 413 nm Tune-Out Wavelength at Which the Atomic Polarizability Vanishes
B. M. Henson, R. I. Khakimov, R. G. Dall +3
We present the first measurement for helium atoms of the tune-out wavelength at which the atomic polarizability vanishes. We utilise a novel, highly sensitive technique for precise…
