“…In the quasi-1D limit, an effective antidipolar interaction can also be achieved simply by a tilt of the dipole polarization angle [48][49][50]. Experiments with ultracold polar molecules have also shown that microwave shielding with circularly polarized light can induce a rapid rotation and hence antidipolar interactions between molecules [51,52]. For single-component condensates, dipole tunability has been predicted to alter vortex-vortex interactions [53], stabilize 3D dark [54] and 2D bright solitons [55,56], induce straight-to-helical vortex transitions [57], create roton excitations in the quasi-1D limit [58], and produce pancake-shaped droplets [59][60][61].…”

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.
