Query: Improved Green's Function Measurement for Hybridization Expansion
  Quantum Monte Carlo   We present an algorithm for measurement of the Green's function in the
hybridization expansion continuous-time quantum Monte-Carlo based on continuous
estimators. Compared to the standard method, the present algorithm has similar
or better accuracy with improvement notable especially at low perturbation
orders and high frequencies. The resulting statistical noise is weakly
correlated so high-accuracy data for the numerical analytical continuation can
be produced.
