Electrostriction in a Bose-Einstein Condensate of Dipolar Molecules
Haneul Kwak, Ian Stevenson, Weijun Yuan +5
The recent creation of a Bose-Einstein condensate (BEC) of dipolar molecules has opened a new frontier for many-body quantum systems in which dipolar interactions can drive novel s…
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…
