Structural symmetry effects on the competition of density waves and superconductivity in bilayer nickelates

Steffen Bötzel, Aiman Al-Eryani, Jun Zhan +4

We investigate the interplay between spin-density-wave (SDW) order and superconductivity in the bilayer nickelate LaNiO using the functional renormalization group~(fRG)…

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…

BosonFlow: A C++ codebase for dynamic fRG and single-boson exchange in correlated fermion systems

Aiman Al-Eryani, Miriam Patricolo, Kilian Fraboulet

We present a unified C++ implementation of the functional renormalization group and the parquet equations within the single-boson exchange formalism for several paradigmatic tight-…

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…

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…
