Abstract
While the chiral linear Luttinger liquid is integrable via bosonization, its nonlinear counterpart does not admit of an analytic solution. Nonetheless, the authors find a number of exact eigenstates for a large family of density-density interaction terms. These quantum many-body scar states are embedded in a continuum of strongly correlated excited states. They exhibit identically zero momentum-space entanglement. Among other properties, this sets them apart from many previous examples of quantum many-body scars.
