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…
Screening and effective RPA-like charge susceptibility in the extended Hubbard model
Aiman Al-Eryani, Sarah Heinzelmann, Kilian Fraboulet +2
We generalize the recently introduced single-boson exchange formalism to nonlocal interactions. In the functional renormalization group application to the extended Hubbard model in…
Single-boson exchange formulation of the Schwinger-Dyson equation and its application to the functional renormalization group
Miriam Patricolo, Marcel Gievers, Kilian Fraboulet +6
We extend the recently introduced single-boson exchange formulation to the computation of the self-energy from the Schwinger--Dyson equation (SDE). In particular, we derive its exp…
Mott transition and pseudogap of the square-lattice Hubbard model: results from center-focused cellular dynamical mean-field theory
Michael Meixner, Henri Menke, Marcel Klett +4
The recently proposed center-focused post-processing procedure [Phys. Rev. Research 2, 033476 (2020)] of cellular dynamical mean-field theory suggests that central sites of large i…
Entangled magnetic, charge, and superconducting pairing correlations in the two-dimensional Hubbard model: a functional renormalization-group analysis
Sarah Heinzelmann, Alessandro Toschi, Sabine Andergassen
Using the recently introduced multiloop extension of the functional renormalization group, we compute the magnetic, density, and superconducting susceptibilities of the two-dimensi…
Single-boson exchange functional renormalization group application to the two-dimensional Hubbard model at weak coupling
Kilian Fraboulet, Sarah Heinzelmann, Pietro M. Bonetti +4
We illustrate the algorithmic advantages of the recently introduced single-boson exchange (SBE) formulation for the one-loop functional renormalization group (fRG), by applying it…
