Description
Since the realization of the first dipolar Bose–Einstein condensate (BEC) of strongly magnetic atoms, long-range and anisotropic dipole–dipole interactions have enabled the emergence of novel quantum phases driven by interaction-induced density modulations. Among these, the most remarkable is the supersolid phase, which simultaneously combines crystalline order with global phase coherence. In particular, the recent achievement of two-dimensional supersolidity has opened a new avenue for exploring the system’s rotational response. In this talk, I will present the most recent theoretical and experimental results on vortex nucleation in two-dimensional supersolids and the subsequent rich and intriguing vortex-crystal dynamics. Finally, I will show an application of rotating dipolar supersolids, i.e. the possibility to simulate “glitches”, instantaneous jumps of the rotation frequency occurring due to the internal vortex dynamics, akin to observations in neutron stars.
