Quantum versus classical quenches and the broadening of wave packets
K. Schönhammer
The time dependence of one-dimensional quantum mechanical probability densities is presented when the potential in which a particle moves is suddenly changed, called a quench. Quan…
Functional renormalization group approach to correlated fermion systems
Walter Metzner, Manfred Salmhofer, Carsten Honerkamp +2
Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon lowering the energy scale, collective phenomena, bound states, and new effective degrees of f…
Full counting statistics for noninteracting fermions: Joint probability distributions
L. Inhester, K. Schonhammer
The joint probability distribution in the full counting statistics (FCS) for noninteracting electrons is discussed for an arbitrary number of initially separate subsystems which ar…
A finite-frequency functional RG approach to the single impurity Anderson model
C. Karrasch, R. Hedden, R. Peters +3
We use the Matsubara functional renormalization group (FRG) to describe electronic correlations within the single impurity Anderson model. In contrast to standard FRG calculations,…
A junction of three quantum wires: restoring time-reversal symmetry by interaction
X. Barnabe-Theriault, A. Sedeki, V. Meden +1
We investigate transport of correlated fermions through a junction of three one-dimensional quantum wires pierced by a magnetic flux. We determine the flow of the conductance as a…
Comment on ``Bethe Ansatz Results for the 4f-Electron Spectra of a Degenerate Anderson Model ''
O. Gunnarsson, K. Schonhammer
In a recent letter, Zvyagin calculates the density of states for 4f electrons coupled to a conduction band in the framework of the Bethe ansatz (BA) solution for the degenerate And…
