Multiloop functional renormalization group from single bosons
Kilian Fraboulet, Aiman Al-Eryani, Sarah Heinzelmann +2
The functional renormalization group (fRG) is an established tool in the treatment of correlated electron systems, notably for the description of competing instabilities. In recent…
Functional renormalization with interaction flows: A single-boson exchange perspective and application to electron-phonon systems
Aiman Al-Eryani, Marcel Gievers, Kilian Fraboulet
The functional renormalization group (fRG) is acknowledged as a powerful tool in quantum many-body physics and beyond. On the technical side, conventional implementations of the fR…
Diagrammatic bosonization, aspects of criticality, and the Hohenberg-Mermin-Wagner theorem in parquet approaches
Aiman Al-Eryani
The parquet equations present a cornerstone of some of the most important diagrammatic many-body approximations and methods currently on the market for strongly correlated material…
Relativistic Mott transition and high-order van Hove singularity in twisted double bilayer WSe: mean-field and functional renormalization group study
Bilal Hawashin, Julian Kleeschulte, David Kurz +2
Experiments on twisted double bilayer tungsten diselenide have demonstrated that moir'e semiconductors can realize a relativistic Mott transition, i.e., a quantum phase transition…
Intertwined fluctuations and isotope effects in the Hubbard-Holstein model on the square lattice from functional renormalization
Aiman Al-Eryani, Sabine Andergassen, Michael M. Scherer
Electron-electron and electron-phonon interactions are responsible for the formation of spin, charge, and superconducting correlations in layered quantum materials. A paradigmatic…
