Bose-Luttinger liquids

Abstract: In this talk I will explain the physics behind a new class of quantum phases of matter known as ``Bose-Luttinger liquids''. A Bose-Luttinger liquid is a phase of matter which in some respects can be thought of as a metal, but with charge carriers that are bosons, instead of electrons. For condensed matter theorists, these phases are interesting because they provide easy-to-understand examples of metallic systems without quasiparticles, and may help explain some interesting quantum critical phenomena in certain types of helical magnets. For high-energy theorists, they are interesting because they provide examples of RG fixed points with infinitely many marginal deformations, which can nonetheless be described using the technology of 2d CFT. This talk will be based on the preprint arXiv:2101.02197.
