The authors theoretically investigate theoretically exotic phases of matter, dubbed ``Bose-Luttinger liquids,'' which can loosely be thought of as bosonic Fermi liquids. Despite being bosonic and consequently lacking degeneracy pressure, these systems posses a bosonic analog of a Fermi surface. Unlike Fermi liquids, however, these systems have no quasiparticles, and exhibit operators whose scaling dimensions can be tuned continuously. The authors suggest that these ideas may be relevant for understanding the non-Fermi-liquid phase of MnSi.
