Scientists have explored superstrength through excitations in a spin-orbitally coupled Bose-Einstein condensate, which serves as a flexible experimental platform for synthetic quantum systems.[2] This condensate hosts a band phase, which is an example of a supersolid state of matter.[2] They achieved direct imaging of the fringes in situ and observed excitations of both the superfluid and the crystal.[2] They investigated the hydrodynamics of the superfluid and revealed a band compression mode, demonstrating that the system has a compressible crystalline structure.[2] By softening the frequency of this mode, they determined the transition point to superstrength.[2] The results confirm spin-orbit coupled superstrengths as an ideal platform for studying superstrength and its dynamics.[2]
