dc.descriptionWe present a Maximum Entropy method (MEM) for obtaining dynamical spectra from Quantum Monte Carlo data which have a sign problem. By relating the sign fluctuations to the norm of the spectra, our method properly treats the correlations between the measured quantities and the sign. The method greatly improves the quality and the resolution of the spectra, enabling it to produce good spectra even for poorly conditioned data where standard MEM fails.
