Liquid-gas transition and coexistence in ground-state bosons with spin twist

We study the thermodynamic liquid-gas transition and coexistence (LGTC) for ground-state bosons under contact interactions. find that LGTC can be facilitated by mismatch of spin polarization, dubbed "spin twist," between single-particle interaction channels with degrees freedom. Such a twist uniquely stabilizes gas phase creating an effective repulsion low-density bosons, thereby enabling in presence quantum droplet at much larger density. have demonstrated scheme binary subject to Rabi coupling magnetic detuning, where conveniently tuned their characterized discontinuous density profile harmonic trap. The generalized wide class systems competing orders.
