Fermionic wave functions from neural-network constrained hidden states

We introduce a systematically improvable family of variational wave functions for the simulation of strongly correlated fermionic systems. This family consists of Slater determinants in an augmented Hilbert space involving “hidden” additional fermionic deg ...

Improving Performance and Accuracy of Hybrid-Functional Based Molecular Dynamics in Plane Waves

Martin Peter Bircher

The simulation of condensed matter in first principles Molecular Dynamics (FPMD) heavily relies on Kohn-Sham Density Functional Theory (KS-DFT) calculations. The accuracy of such simulations is governed by the reliability of the underlying potential energy ...

Quantifying Electronic Phenomena in Organic Chromophores

Antonio Prlj

Challenging ground and excited state problems in the chemistry of common organic chromophores are investigated with state-of-the-art quantum chemical methods. We present a comprehensive excited state molecular dynamics analysis of (a) fundamental building ...

First-principles investigation of symmetric and antisymmetric exchange interactions of SrCu2(BO3)(2)

Frédéric Mila

We report on a first-principles investigation of the electronic structure and of the magnetic properties of the quasi-two-dimensional Mott insulator SrCu2(BO3)(2). Based on the hopping integrals and Coulomb interactions calculated with local-density approx ...

Multiplets of free d- and f-metal ions: A systematic DFT study

Alain Borel

In this work we apply in a systematic way our multi-determinantal model to calculate the fine structure of the whole atomic multiplet manifold. The key feature of this approach is the explicit treatment of near-degeneracy correlation using ad hoc configura ...
