Join the frontier of condensed matter research and tackle the “mother of all models”. The Hubbard model in 2 and larger dimensions is an unsolved paradigm of modern condensed matter physics and believed to hold the key for understanding emergent phenomena like  high-temperature superconductivity, qu...

Yorick L. A. Schmerwitz, Louis Thirion, Gianluca Levi, Elvar Ö. Jónsson, Pavlo Bilous, Hannes Jónsson, and Philipp Hansmann We apply a recently proposed computational protocol for a neural-network-supported configuration interaction calculation to the paradigmatic N2 molecule. By comparison of corr...

Pavlo Bilous, Louis Thirion, Henri Menke, Maurits W. Haverkort, Adriana Pálffy, Philipp Hansmann A deep-learning approach to optimize the selection of Slater determinants in configuration interaction calculations for condensed-matter quantum many-body systems is developed. We exemplify our algorith...
