Query: Integrable Open Spin Chains and the Doubling Trick in N = 2 SYM with
  Fundamental Matter   We demonstrate that the one-loop anomalous dimension matrix in N = 2 SYM with
a single chiral hypermultiplet of fundamental matter, which is dual to AdS_5 X
S^5 with a D7-brane filling AdS_5 and wrapped around an $^3 in the S^5, is an
integrable open spin chain Hamiltonian. We also use the doubling trick to
relate these open spin chains to closed spin chains in pure N = 4 SYM. By using
the AdS/CFT correspondence, we find a relation between the corresponding open
and closed strings that differs from a simple doubling trick by terms that
vanish in the semiclassical limit. We also demonstrate that in some cases the
closed string is simpler and easier to study than the corresponding open
string, and we speculate on the nature of corrections due to the presence of
D-branes that this implies.
