A stripe phase with supersolid properties in spin–orbit-coupled Bose–Einstein condensates

Spin–orbit coupling in Bose–Einstein condensates creates a density modulation, which is a stripe phase with supersolid properties. Supersolids exhibit long-range order, just like normal solids, while simultaneously displaying superfluid properties. This state of matter has been extremely difficult to generate and previous results that have suggested supersolidity in helium are yet to be unambiguously verified. Here, Jun-Ru Li and colleagues...
