New paper published in Physical Review Research

We are happy to anounce that the recent work by Jakša Vučičević, Pavle Stipsić and Michel Ferrero has been published in Physical Review Research. The paper presents an analytical solution of the imaginary time integrals that appear in quantum many-body perturbation theory, and its application in the study of the two-dimensional Hubbard model using diagrammatic Monte Carlo algorithms.

PARADOX upgrade complete

We are thrilled that the final pieces of the upgrade for our PARADOX cluster have been put into production. Our computational resources are now nearing 1500 CPUs.

J. Vučičević presents on Simons Collaboration on the Many Electron Problem meeting

Today Jakša Vučičević participated in an online workshop, organized by the Simons foundation funded Collaboraton on the Many Electron Problem.
The topic of the meeting was diagrammatic Monte Carlo, and Jakša presented his most recent work, done in collaboration with P. Stipsić and M. Ferrero (see also this) in a 30 minute talk, followed by a discussion. Other speakers in the Friday session were James Leblanc, Nikolay Prokof’ev and Olivier Parcollet, and among other speakers who presenting on Monday and Tuesday were also Kristjan Haule, Boris Svistunov and Evgeny Kozik. The event attracted more than 50 participants.
