We are pleased to announce the publication of our new paper in SciPost Physics. In our article, we investigate dynamical mean-field calculations of the three-band Emery model, focusing on the one- and two-particle levels for material-realistic parameters of high-(Tc) superconductors. Our results sho...

We are pleased to announce our new joint publication with Theoretical Chemsits at the University of Iceland in the Journal of Chemical Theory and Computation (JCTC). In this work, we combine Hartree–Fock with a neural-network-supported quantum-cluster solver to introduce the Neural-Network Configura...

We are pleased to announce the publication of our new paper in Physical Review B. Our work introduces a neural-network approach to optimize the selection of Slater determinants in configuration interaction (CI) calculations for strongly correlated quantum systems. Using a neural classifier and activ...

SOLAX is an open-source Python solver for fermionic quantum many-body systems with neural-network support. It provides a modular framework—based on the standard formalism of second quantization—for building basis sets, states, and operators, and for solving quantum cluster problems efficiently. Impl...
