Non Fermi liquid scattering and pseudogap: spectral features from a meanfield with partial incoherence of lower dimension

Non-fermi liquid behavior and pseudogap formation are examples of exotic spectral features observed in hole-doped cuprates and some other strongly correlated materials. Considering the necessity of coherence for gap formation, and incoherence for filling the gap with states, these characteristic features are often believed to originate from strong fluctuation in the critical region or vicinity of a long-range order. Here we propose that these features can also come from coupling to an unconventional ''Bose metal'' meanfield, which contains perfect coherence and partial phase incoherence of lower dimension. Such a meanfield can exist in the Bose metal phase and thus can act in a much wider region of the phase diagram beyond just the critical region.
