Welcome! We are a condensed matter theory group working on strongly correlated electrons in both solids and molecules from a computational perspective.
Current Group Members
- Mauricio Rodríguez Mayorga (Postdoc, NanoX): Mauricio has joined the group in Jan 2026 as part of the GEIST project. His research with us concerns describing shake-up satellites in molecular photo-emission spectra from first principles by combining the ghost Gutzwiller Ansatz with computational chemistry solvers.

My research concerns the modelling of electronic correlation in both solid state and molecular systems. Leveraging their common features while heeding their differences, I work on bridging traditional theoretical approaches for both of them to gain new insight and improve their respective descriptions. My interests include:
- Embedding models of strong correlation, such as dynamical mean-field theory or Gutzwiller-based approaches.
- High order vertex corrections in many-body perturbation theory.
- Quantum algorithms for simulating the many-body problem.
I am very lucky and grateful to count with wonderful collaborators. Please let me know if I forgotten anyone!!
