Experience
Assistant Professor, Charles University
January 2017 – Present
- In an international collaboration, I drew a roadmap of an emergent new research discipline (Molecular electronics), published in Reviews of Modern Physics
- Discovered interference effect in atomic spin chains on a metallic surface – “Kondo chains” – using many-body perturbation theory for a multi-impurity Anderson model
- I supervised application of a Numerical Renormalization Group to a molecular Kondo problem
- Supervising a PhD thesis on the application of qp-GW to quantum transport
- Teaching, organization (committee work) & collaboration with international groups (Oxford, Columbia U, Kolkata, Regensburg, Delft, Leiden, San Sebastian)
- Communication: designing personal web-page to communicate with students and managing the News section of the department web-page
- Proposal writing: Attracted 615 000 € from public funding agencies (2 grants)
Assistant Professor, University of Regensburg
September 2014 – July 2016
- Discovered a surprising trend in excitation energies of linear molecules combining ab-initio DFT with a lattice model (DMRG, with P. Schmitteckert)
- Coding: My code (FORTRAN2003, using math kernel libraries) was published as a part of the SIESTA computer package, used by thousands of researchers
- Communication: publication of research in high-impact scientific journals (e.g. Nature Publishing Group)
- Techniques: DFT on a supercomputer architecture
- Teaching: undergraduate physics courses, designing problem classes, lecturing
Postdoctoral Researcher, Karlsruhe Institute of Technology (KIT)
October 2011 – September 2014
- Institute for Nanotechnology (INT KIT)
- Density-functional theory for the non-equilibrium electron transport through molecular junctions in an emerging research field: Molecular Electronics
- Communication: aim of the research projects was to combine experimental data and my own theoretical models to formulate a concise story, presented at international conferences and in high-impact research journals
- Mentoring undergraduate students
Graduate Scholar, Catalan Institute of Nanoscience and Nanotechnology
OCTOBER 2007 – JUNE 2011
- Ph.D. thesis “Molecular Kondo problem: First-principles approach for scanning-tunneling microscope studies”
- Timely experimental Kondo signals could not be captured by state-of-the-art ab-initio simulations. I developed a technique that merged DFT and many-body techniques. The procedure involved
- Mapping of DFT on the Anderson impurity model (downfolding) via Wannier orbitals
- Self-consistent diagrammatic perturbation theory for the Anderson model
- Won a competitive 4-year scholarship

3 representative publications
- Advances and challenges in
single-molecule electron transport
F. Evers, R. Korytár, S. Tewari, J.M. van Ruitenbeek, Reviews of Modern Physics (2020)- We drew a roadmap of an emergent field of Molecular Electronics. The theoretical part emphasizes both mean-field and many-body approaches, e.g. lattice models, non-equilibrium, DFT, GW
- Real
space manifestations of coherent screening in atomic scale Kondo
lattices
M. Moro-Lagares, R. Korytár, M. Piantek et al. Nature Communications (2019)- The experimentalists built an atomic Kondo lattice and I explained why the Kondo peaks enhance at the edges of the chain
- I designed and solved many-body perturbation theory for the multi-impurity Anderson model
- Signature of the Dirac
cone in the properties of linear oligoacenes
R. Korytár, D. Xenioti, P. Schmitteckert et al. Nature Communications (2014)- When oligoacenes increase their length, I found that their excitation gaps oscillate
- My band-structure calculations were complemented by GW and DMRG
