This note addresses the problem of constructing a proper bosonized description of the collective modes in strongly interacting (non-)Fermi liquids which is specific to two spatial dimensions. Although, in a mild form, this subtlety exists in the Fermi liquid as well, the discussion focuses on the effects of long-ranged and/or retarded interactions which can completely destroy the fermionic quasiparticles. The present analysis also provides a further insight into the nature and properties of the collective bosonic modes in such systems.

  1. Berry Phase and Quantum Oscillation from Multi-orbital Coadjoint-orbit Bosonization

    cond-mat.str-el 2024-12 conditional novelty 7.0 of 10

    Coadjoint-orbit bosonization shows the de Haas-van Alphen phase shift is governed by the static anomalous Hall conductance, with Berry-curvature corrections to the Lifshitz-Kosevich amplitude.

  2. Electrons Lost in Phase Space

    cond-mat.str-el 2024-12 conditional novelty 6.0 of 10

    Patch bosonization cannot be used for a two-dimensional metal at a quantum critical point, except in artificial small- or large-flavor limits.
