Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon
lowering the energy scale, collective phenomena, bound states, and new effective degrees …

Interactions between quasiparticles mediated by a surrounding environment are ubiquitous
and lead to a range of important effects from collective modes of low-temperature quantum …

We use the Matsubara functional renormalization group (FRG) to describe electronic
correlations within the single impurity Anderson model. In contrast to standard FRG …

We study a mixture of strongly interacting bosons and spinless fermions with on-site
repulsion in a three-dimensional optical lattice. For this purpose we develop and apply a …

We investigate a cold-atom mixture of spinless bosons and fermions in two-dimensional
optical lattices. In the presence of a nested Fermi surface, the bosons may develop a …

We consider a system of repulsively interacting Bose-Fermi mixtures of spin-polarized
uniform atomic gases at zero temperature. We examine possible realization of p-wave …

Superfluid-insulator transitions in a one-dimensional mixture of two-color fermions and
scalar bosons are studied within the framework of the Bose-Fermi-Hubbard model. Zero …

We study numerically a one-dimensional mixture of spin-1 2 fermions and scalar bosons in
the hard-core limit. Considering repulsive fermion-fermion and boson-fermion interactions …

We give a detailed discussion of the recently developed generalized dynamical mean-field
theory (GDMFT) for a mixture of bosonic and fermionic particles. We show that this method is …

We study transport properties of quantum impurity systems using the functional
renormalization group. The latter is an RG-based diagrammatic tool to treat Coulomb …
