When holes are doped into the copper-oxide plane of high-temperature superconductors, the metallic state that ensues is not characterized  by a continuous closed surface in momentum space as dictated by the standard theory of metals.  Rather, the surface is truncated, forming what is referred to as a Fermi arc.  I address two questions in this  talk.  First, can a phase with Fermi arcs preserve Luttinger's  theorem? Second, can gauge-gravity duality with tailored bulk interactions generate Fermi arcs from    a Mott state?  From exact models, I will show that Fermi arcs involve  a breakdown of Luttinger's theorem and that Fermi arcs evolve from a  Mott insulator by the breaking of parity in the boundary theory.  The Mott insulator arises from the breaking of bulk chiral symmetry.
