abstract
Realizing Bose-Einstein condensation of polar molecules is a long-standing challenge in ultracold physics and quantum science due to near-universal two-body collisional losses. Here, we report the production of a Bose-Einstein condensate of ground-state sodium-rubidium molecules via high efficiency evaporative cooling, with losses suppressed using the dual microwave shielding technique. The ability to tune the dipolar interaction between these ultracold polar molecules is crucial for producing the condensate and enables exciting prospects for future applications. We explore different regimes of dipolar interactions, realizing both the gas phase and the quantum droplet phase of the molecular condensate. This work opens new avenues for investigating quantum matter with strong dipolar interactions and for quantum simulation of long-range many-body systems.

Ground-state path integral Monte Carlo simulations of NaCs polar molecules with double microwave shielding show self-bound droplets forming above an ellipticity threshold of ~3 degrees, with an estimated superfluid fraction up to 0.8.
Microwave dressing breaks rotational symmetry in polar-molecule interactions, producing metastable droplet arrays as non-equilibrium states while suppressing the crystalline phase expected for antidipolar cases.
Self-bound quantum droplets exhibit nonmonotonous dependence on non-axisymmetric DDI strength, tighter binding with more particles, collapse at low s-wave scattering length, and direction-dependent collision outcomes ranging from rebound to fragmentation.
Superspecial curves of genus 4 exist for almost all primes p with 7<p<10^6, and of genera 5 and 6 for almost all primes with 7≤p<10^5, via completely decomposable Howe curves.
Simulations of confined polar molecules reveal a bilayer crystal phase stabilized by increasing confinement and evidence of layered superfluid states with inter-layer coherence.
In-situ imaging of quasi-2D 166Er Bose gas reveals magnetostriction crossover from anisotropic superfluid to isotropic normal phase, supported by a quasi-2D Hartree-Fock mean-field thermometry framework that fits temperature and chemical potential from a single density profile.
Light-induced losses dominate DyK Feshbach molecule decay in most near-IR traps, but near 2000 nm collisional losses appear and are suppressed by an order of magnitude for the most weakly bound dimers due to Pauli exclusion.
Microwave shielding on the n=1→2 transition prevents collisions between ultracold polar molecules without producing bound states that would enhance three-body recombination.
