Query: Dynamical Gap and Cuprate-like Physics from Holography   We study the properties of fermion correlators in a boundary theory dual to
the Reissner-Nordstr\"om AdS_{d+1} background in the presence of a bulk dipole
(Pauli) interaction term with strength p. We show that by simply changing the
value of the parameter p we can tune continuously from a Fermi liquid (small
p), to a marginal Fermi liquid behavior at a critical value of p, to a generic
non-Fermi liquid at intermediate values of p, and finally to a Mott insulator
at large values of the bulk Pauli coupling. As all of these phases are seen in
the cuprate phase diagram, the holographic model we study has the key elements
of the strong coupling physics typified by Mott systems. In addition, we extend
our analysis to finite temperature and show that the Mott gap closes. Of
particular interest is that it closes when the ratio of the gap to the critical
temperature is of the order of ten. This behavior is very much similar to that
observed in the classic Mott insulator VO_2. We then analyze the
non-analyticities of the boundary theory fermion correlators for generic values
of frequency and momentum by calculating the quasi-normal modes of the bulk
fermions. Not surprisingly, we find no evidence for the dipole interaction
inducing an instability in the boundary theory. Finally, we briefly consider
the introduction of superconducting condensates, and find that in that case,
the fermion gap is driven by scalar-fermion couplings rather than by the Pauli
coupling.
