In this work we present a comprehensive analysis of collective electronic fluctuations and
their effect on single-particle properties of the Hubbard model. Our approach is based on a …

We study the microscopic mechanism controlling the interplay between local charge and
local spin fluctuations in correlated electron systems via a thorough investigation of the …

We present a reformulation of the functional renormalization group (fRG) for many-electron
systems, which relies on the recently introduced single-boson exchange (SBE) …

The recently introduced single-boson exchange (SBE) decomposition of the four-point
vertex of interacting fermionic many-body systems is a conceptually and computationally …

Correlated electron systems may give rise to multiple effective interactions whose combined
impact on quasiparticle properties can be difficult to disentangle. We introduce an …

We introduce a diagrammatic multi-scale approach to the Hubbard model based on the
interaction-irreducible (multi-boson) vertex of a small cluster embedded in a self-consistent …

We analyze possible ways to calculate magnetic exchange interactions within the density
functional theory plus dynamical mean-field theory (DFT+ DMFT) approach in the …

In this paper, we revisit the antiferromagnetic (AF) phase diagram of the single-band three-
dimensional half-filled Hubbard model on a simple cubic lattice studied within the dynamical …

The parquet approach to vertex corrections is unbiased but computationally demanding.
Most applications are therefore restricted to small cluster sizes or rely on various simplifying …

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 to …
