Query: Fermi arcs and the hidden zeros of the Green's function in the pseudogap
  state   We investigate the low energy properties of a correlated metal in the
proximity of a Mott insulator within the Hubbard model in two dimensions. We
introduce a new version of the Cellular Dynamical Mean Field Theory using
cumulants as the basic irreducible objects. These are used for re-constructing
the lattice quantities from their cluster counterparts. The zero temperature
one particle Green's function is characterized by the appearance of lines of
zeros, in addition to a Fermi surface which changes topology as a function of
doping. We show that these features are intimately connected to the opening of
a pseudogap in the one particle spectrum and provide a simple picture for the
appearance of Fermi arcs.
