Observation of vortices in a dipolar supersolid 偶極超固體中渦旋的觀測 ▲ 作者:Eva Casotti, Elena Poli et al. ▲鏈接: https://www.nature.com/articles/s41586-024-08149-7 ▲摘要: 在此,掌握了在偶極氣體和具有二維結(jié)晶順序的超固體中產(chǎn)生渦旋的方法后,我們報(bào)告了超固體相(SSP)中渦旋的理論研究和實(shí)驗(yàn)觀察。我們的工作揭示了未調(diào)制和調(diào)制量子流體之間渦旋形成動(dòng)力學(xué)的根本差異。 這為研究具有許多存在于不同領(lǐng)域——如量子晶體和中子星發(fā)——中的自對(duì)稱性破缺的奇異量子系統(tǒng)的流體動(dòng)力學(xué)特性打開了大門。 ▲ Abstract: Here, with the prerequisite pieces at our disposal, namely a method to generate vortices in dipolar gases and supersolids with two-dimensional crystalline order, we report on the theoretical investigation and experimental observation of vortices in the supersolid phase (SSP). Our work reveals a fundamental difference in vortex seeding dynamics between unmodulated and modulated quantum fluids. This opens the door to study the hydrodynamic properties of exotic quantum systems with numerous spontaneously broken symmetries, in disparate domains such as quantum crystals and neutron stars. |
