In my talk, I will present recent experiments where we leverage the tunable interaction properties of potassium atoms to realize robust supersolids in a spin-orbit coupled Bose-Einstein condensate, and to observe in situ for the first time their modulated density profiles. We demonstrate that, unlike in cavity supersolids, the supersolid stripe spacing is not fixed: it varies with the spin-orbit coupling strength and hosts a stripe compression mode. Moreover, we measure the softening of the stripe compression mode frequency with increasing spin-orbit coupling strength, revealing in this way the supersolid phase transition. Our experiments establish spin-orbit coupled Bose-Einstein condensates as an attractive alternative platform to investigate supersolidity, and provide an excellent starting point to explore its interplay with quantum fluctuations and external lattice potentials.
