“…Strongly dipolar condensate mixtures, comprised of two different species, are now available in experiments [38][39][40][41] and these open new possibilities for supersolidity. In the dipoledominated regime, where the contact interactions are weaker than the dipole-dipole interactions (DDIs), supersolid phases have been predicted in both the miscible [42,43] and immiscible regimes [40], with both situations requiring quantum stabilization to counterbalance the net attractive mean-field interactions. However, a distinguishing feature of two-component systems is that the relevant excitation spectra become the spin (out-of-phase) and density (inphase) branches.…”

We present a theoretical study of a mixture of antidipolar and nondipolar Bose-Einstein condensates confined to an infinite tube. We predict the presence of a spin roton and its associated instability, which triggers a continuous unmodulated-to-supersolid phase transition. We characterize the phase diagram of the binary system, ranging from the quasi-1D to the radial Thomas-Fermi (elongated 3D) regimes. We also present the dynamic formation of supersolids following a quench from the uniform miscible phase, which maintains phase coherence across the system.
