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...

Yi-Ting Tseng, M. O. Malcolms, Henri Menke, Marcel Klett, Thomas Schäfer, and P. Hansmann We compare the dynamical mean-field descriptions of the single-band Hubbard model and the three-band Emery model at the one- and two-particle level for parameters relevant to high-Tc superconductors. We show...

The unconventional superconductor Sr2RuO4 has long served as a benchmark for theories of correlated-electron materials. The determination of the superconducting pairing mechanism requires detailed experimental information on collective bosonic excitations as potential mediators of Cooper pairing. We...

In 2018 we predicted chiral d-wave superconductivity in hole-doped X:Si(111) (X=Sn,Pb) ad-atom systems (see Figure). Now - 5 years later - experimentalists confirm our prediction in boron doped Sn:Si(111) in a Nature physics article.

Stefan Käser, et al. We study the superconducting gap function of Sr2RuO4. By solving the linearized Eliashberg equation with a correlated pairing vertex extracted from a dynamical mean-field calculation we identify the dominant pairing channels. An analysis of the candidate gap functions in orbita...
