Abstract
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.

List of changes
List of changes:
- Abstract modified to better highlight important features of our work
- Included stronger motivational statements in the introduction, highlighting the open questions that we answer
- Section 3: Improved explanation of physical interpretation of the roton instability
- Section 4.1: Refined discussion of superfluid fractions, and their relation to the reduction of combined moment of inertia
- Section 4.2: clarified and extended the discussion on the miscible to SS-SS transition, including a physical explanation for the behaviour of the phase boundary
- Additions to conclusions, including references to specific physical experimental candidate systems and including a clarified comment on the possibility of future studies of Kibble-Zurek mechanism in supersolids
- Minor numerical artifacts for a couple of data points in Fig. 5 have been corrected. Vast majority of data points unchanged and conclusions unaffected.
