Finite-Temperature Flat-Band Ferromagnetism in the Kagome Hubbard Model
Alon Strugatsky, Roser Valení, Roser Valentí +1
Kagome metals exhibit a rich interplay of topology, electronic correlations, and lattice dynamics. Recent discoveries of Kagome materials with a flat band near the Fermi level have…
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…
Exact downfolding and its perturbative approximation
Jonas B. Profe, Jakša Vučičević, 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…
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…
The kagome Hubbard model from a functional renormalization group perspective
Jonas B. Profe, Lennart Klebl, Francesco Grandi +5
The recent discovery of a variety of intricate electronic order in kagome metals has sprouted significant theoretical and experimental interest. From an electronic perspective on t…
divERGe implements various Exact Renormalization Group examples
Jonas B. Profe, Dante M. Kennes, Lennart Klebl
We present divERGe, an open source, high-performance C/C++/Python library for functional renormalization group (FRG) calculations on lattice fermions. The versatile model interface…
