What is Chiral vortex-line liquid of three-dimensional interacting Bose systems with moat dispersion about?

We formulate and investigate a novel quantum state, the Chiral Vortex-Line Liquid (CVLL), emerging in three-dimensional interacting Bose systems exhibiting moat-band dispersions. Such dispersions feature extensive degeneracy along closed manifolds in momentum space, significantly amplifying quantum fluctuations that suppress conventional Bose-Einstein condensation. By extending the two-dimensional Chern-Simons flux-attachment transformation to three dimensions through a combination of planar CS phases and Jordan-Wigner fermionization along vortex lines, we construct the CVLL state, characterized by nontrivial vortex-line excitations with topological properties. We develop an associated topological field theory in a curved spatial geometry and study the low-energy effective theory of the CVLL state. Using Monte Carlo simulations, we numerically determine the CVLL ground state's chemical potential for interacting bosons in cylindrical moat-band geometries and demonstrate that the CVLL phase energetically outcompetes traditional condensate phases at low densities, highlighting its relevance to experimental platforms including frustrated quantum magnets, ultracold atomic gases, physics
