Descriptions of our long-term research programs

P1: Systematic Framework of Functional Theories for Strongly Correlated Electrons
This project forms the core of our ERC-funded research programme BeyondDFT. Its goal is to develop a next-generation theoretical framework capable of accurately describing strongly correlated quantum systems --- an area where conventional density-functional theory (DFT), despite being the workhorse of electronic-structure calculations, fundamentally fails. We aim to advance one-particle reduced density matrix functional theory (1RDMFT) into a practical, predictive, and systematically improvable alternative to DFT.

The project sits at the interface of quantum chemistry, mathematical physics, and quantum information science. It offers opportunities to contribute both to conceptual advances in many-body theory and to concrete computational methods that may transform future electronic-structure modelling. We are recruiting motivated PhD students and postdoctoral researchers to work on theory development, mathematical analysis, and computational implementation within this ambitious research programme.

P2: OpenMolcas: Code development for quantum chemistry 
This project aims to refine our group’s recently developed scheme for active space selection and thoroughly benchmark its performance across a range of challenging molecular systems. A central goal is the integration of this method into the widely used OpenMolcas software package, contributing to its further development and accessibility for the quantum chemistry community.

P3: Tensor network methods for quantum chemistry
We investigate how tools from quantum information theory can uncover and exploit the correlation structure of molecular ground states, with the goal of improving tensor network approaches for quantum chemistry. This includes developing orbital optimization strategies in QC-DMRG to enhance locality, as well as novel hybrid methods to better capture dynamical correlation.

P4: Foundation of quantum computing: fermionic systems
The ultimate goal of our research program is to develop more efficient quantum algorithms for determining ground and excited states of interacting many-body quantum systems. This involves foundational and mathematically challenging questions and follows an exploratory approach. A particular focus lies on revealing some universal structures of realistic many-electron wave functions (such as the Kato cusp) which shall then be translated into the context of quantum state preparation and circuit complexity.

P5: Quantum information theory for fermions
We pursue a unified framework for fermionic entanglement and correlation, with particular focus on the connection between particle and mode entanglement. A central conjecture, if confirmed, would replace vague notions such as static and dynamic correlation with a precise and operationally meaningful complexity measure. We also explore how ideas from quantum thermodynamics can sharpen our understanding of chemical bonding.
