Query: Topologically Unquenched QCD: Prospects from an explorative study in
  2-flavour QED(2)   The concept of simulating a variant of QCD with sea quarks which interact
with the gluon configuration only via global gluonic quantities like $\int
F\tilde F dx$ and $\int FF dx$ is tested for the case of the massive 2-flavour
Schwinger model. It is found to amount to an importance sampling method which
generates -at essentially the costs of a quenched run- an ensemble in between a
full and a quenched one, thus providing a competitive alternative to the
quenched approximation.
