Exact downfolding and its perturbative approximation
Jonas B. Profe, JakÅ¡a VuÄiÄeviÄ, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Pressure Tuning of Electronic Correlations and Flat Bands in CsCrSb
Maria Chatzieleftheriou, Jonas B. Profe, Ying Li +1
CsCrSb is a newly identified strongly correlated kagome superconductor, characterized by non-Fermi-liquid behavior at elevated temperatures and intertwined charge- and spin…
Excitonic correlations in the equilibrium and voltage-biased bilayer Hubbard model: multi-orbital two-particle self-consistent approach
Jiawei Yan, Jonas B. Profe, Yuta Murakami +1
We develop a nonequilibrium multi-orbital extension of the two-particle self-consistent theory and apply it to the bilayer Hubbard model as a minimal platform to investigate correl…
Symmetry-breaking-induced topology in FeSe
Mikel GarcÃa-DÃez, Jonas B. Profe, Augustin Davignon +3
FeSe has been one of the most intensively studied iron-based superconductors over the past two decades, exhibiting a wide range of phenomena such as unconventional superconductivit…
Multi-orbital two-particle self-consistent approach -- strengths and limitations
Jonas B. Profe, Jiawei Yan, Karim Zantout +2
Extending many-body numerical techniques which are powerful in the context of simple model calculations to the realm of realistic material simulations can be a challenging task. Re…
