Observation of Self-Bound Droplets of Ultracold Dipolar Molecules
Siwei Zhang, Weijun Yuan, Niccolò Bigagli +4
Ultracold gases of dipolar molecules have long been envisioned as a platform for the realization of novel quantum phases. Recent advances in collisional shielding, protecting molec…
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…
Double Microwave Shielding
Tijs Karman, Niccolò Bigagli, Weijun Yuan +3
We develop double microwave shielding, which has recently enabled evaporative cooling to the first Bose-Einstein condensate of polar molecules [Bigagli et al., Nature 631, 289 (202…
Three-Body Recombination of Ultracold Microwave-Shielded Polar Molecules
Ian Stevenson, Shayamal Singh, Ahmed Elkamshishy +5
A combined experimental and theoretical study is carried out on the three-body recombination process in a gas of microwave-shielded polar molecules. For ground-state polar molecule…
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,…
Observation of Bose-Einstein Condensation of Dipolar Molecules
Niccolò Bigagli, Weijun Yuan, Siwei Zhang +4
Ensembles of particles governed by quantum mechanical laws exhibit fascinating emergent behavior. Atomic quantum gases, liquid helium, and electrons in quantum materials all show d…
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…
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…
