We are happy to announce a new preprint https://arxiv.org/abs/2011.08226 , “Analytical solution for time-integrals in diagrammatic expansions: application to real-frequency diagrammatic Monte Carlo”. This is a very promising new approach to obtaining frequency spectra in strongly correlated systems. The work is done by J. Vučičević in collaboration with MSc student Pavle Stipsić and our long time collaborator from College de France, Paris, Michel Ferrero.
