Fractonic Luttinger liquids and supersolids in a constrained Bose-Hubbard model
Fractonic Luttinger liquids and supersolids in a constrained Bose-Hubbard model
Quantum many-body systems with fracton constraints are widely conjectured to exhibit unconventional low-energy phases of matter. In this work, we demonstrate the existence of a variety of such exotic quantum phases in the ground states of a dipole-moment conserving Bose-Hubbard model in one dimension. For integer boson fillings, we perform …
