Query: On complex Langevin dynamics and zeroes of the measure I: Formal proof
  and simple models   In the complex Langevin approach to lattice simulations at nonzero density,
zeroes of the fermion determinant lead to a meromorphic drift and hence a need
to revisit the theoretical derivation. We discuss how poles in the drift affect
the formal justification of the approach and then explore the various potential
issues in simple models, in a manner that is applicable to heavy dense and full
QCD.
