In the early 1970s, Wilson developed the concept of a fully nonperturbative renormalization
group transformation. When applied to the Kondo problem, this numerical renormalization …

The crossover from fluctuating atomic constituents to a collective state as one lowers
temperature or energy is at the heart of the dynamical mean-field theory description of the …

A major challenge in the field of correlated electrons is the computation of dynamical
correlation functions. For comparisons with experiment, one is interested in their real …

Multipoint vertex functions, and the four-point vertex in particular, are crucial ingredients in
many-body theory. Recent years have seen significant algorithmic progress toward …

The many-body problem is usually approached from one of two perspectives: the first
originates from an action and is based on Feynman diagrams, the second is centered …

We study transport through a quantum dot coupled to normal and superconducting leads
using the numerical renormalization group method. We show that the low-energy properties …

Using analytical arguments and the numerical renormalization group method, we investigate
the spin thermopower of a quantum dot in a magnetic field. In the particle-hole-symmetric …

We employ the recently proposed scattering states numerical renormalization group (SNRG)
approach to calculate I (V) and the differential conductance through a single molecular level …

We present a comprehensive Fermi liquid description for thermoelectric transport and
current noise, applicable to multilevel quantum dots (QD) and magnetic alloys (MA) without …

We investigate the magnetic field dependent thermopower, thermal conductivity, resistivity,
and<? format?> Hall effect in the heavy fermion metal YbRh 2 Si 2. In contrast to reports on …
