超冷分子气体中可宽范围调控的偶极相互作用实现极端损耗抑制

Weijun Yuan1†, Siwei Zhang1†, Niccolò Bigagli1, Haneul Kwak1, Claire Warner1, Tijs Karman2, Ian Stevenson1, Sebastian Will1* Ultracold dipolar molecules hold great promise for the creation of exotic quantum states of matter, but the realization of long- lived molecular bulk samples with strong dipole- dipole interactions has remained challenging. In this work, we realized a collisionally stable gas of ultracold ground state molecules with a lifetime of several seconds. Utilizing double- microwave dressing, we achieved an extreme suppression of inelastic two- and three- body losses by factors of more than 10,000 and 1000, respectively. …
