Rapid generation of metastable helium Bose-Einstein condensates
A. H. Abbas, X. Meng, R. S. Patil +3
We report the realisation of Bose-Einstein condensation (BEC) of metastable helium atoms using an in-vacuum coil magnetic trap and a crossed beam optical dipole trap. A novel quadr…
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…
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…
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…
