Extreme Loss Suppression and Wide Tunability of Dipolar Interactions in an Ultracold Molecular Gas
Weijun Yuan, Siwei Zhang, Niccolò Bigagli +5
Ultracold dipolar molecules hold great promise for the creation of novel quantum states of matter, but the realization of long-lived molecular bulk samples with strong dipole-dipol…
Dressed-State Spectroscopy and Magic Trapping of Microwave-Shielded NaCs Molecules
Siwei Zhang, Weijun Yuan, Niccolò Bigagli +3
We report on the optical polarizability of microwave-shielded ultracold NaCs molecules in an optical dipole trap. While dressing a pair of rotational states with a microwave field,…
A planar cloverleaf antenna for the creation of circularly polarized microwave fields
Weijun Yuan, Siwei Zhang, Niccolò Bigagli +3
We report on the design and characterization of a compact microwave antenna for atomic and molecular physics experiments. The antenna is comprised of four loop antennas arranged in…
Collisionally Stable Gas of Bosonic Dipolar Ground State Molecules
Niccolò Bigagli, Claire Warner, Weijun Yuan +4
Stable ultracold ensembles of dipolar molecules hold great promise for many-body quantum physics, but high inelastic loss rates have been a long-standing challenge. Recently, it wa…
Efficient Pathway to NaCs Ground State Molecules
Claire Warner, Niccolò Bigagli, Aden Z. Lam +4
We present a study of two-photon pathways for the transfer of NaCs molecules to their rovibrational ground state. Starting from NaCs Feshbach molecules, we perform bound-bound exci…
Ultracold Gas of Dipolar NaCs Ground State Molecules
Ian Stevenson, Aden Z. Lam, Niccolò Bigagli +4
We report on the creation of bosonic NaCs molecules in their absolute rovibrational ground state via stimulated Raman adiabatic passage. We create ultracold gases with up to 22,000…
A High Phase-Space Density Gas of NaCs Feshbach Molecules
Aden Z. Lam, Niccolò Bigagli, Claire Warner +5
We report on the creation of ultracold gases of bosonic Feshbach molecules of NaCs. The molecules are associated from overlapping gases of Na and Cs using a Feshbach resonance at 8…
Overlapping Bose-Einstein Condensates of Na and Cs
Claire Warner, Aden Z. Lam, Niccolò Bigagli +3
We report on the creation of dual-species Bose-Einstein condensates (BECs) of Na atoms and Cs atoms. We demonstrate sympathetic cooling of Cs with Na in a magnetic q…
Compact Two-Dimensional Magneto-Optical Trap for Ultracold Atom Setups
Aden Zhenhao Lam, Claire Warner, Niccolò Bigagli +4
We report on the design, implementation, and performance of a compact two-dimensional magneto-optical trap (2D MOT) for cesium. In a small-volume vacuum chamber, the setup uses ces…
Precision measurement of the -asymmetry in spin-polarized decay
B. Fenker, A. Gorelov, D. Melconian +13
Using TRIUMF's neutral atom trap, TRINAT, for nuclear decay, we have measured the asymmetry with respect to the initial nuclear spin in to be $A_β=-0.5707…
Precision measurement of the nuclear polarization in laser-cooled, optically pumped
Benjamin Fenker, John A. Behr, Dan Melconian +18
We report a measurement of the nuclear polarization of laser-cooled, optically-pumped atoms which will allow us to precisely measure angular correlation parameter…
