A real-time study of diffusive and ballistic transport in spin-1/2 chains using the adaptive time-dependent density matrix renormalization group method
S. Langer, F. Heidrich-Meisner, J. Gemmer +2
Using the adaptive time-dependent density matrix renormalization group method, we numerically study the spin dynamics and transport in one-dimensional spin-1/2 systems at zero temp…
Quasiparticles in the Kondo lattice model at partial fillings of the conduction band
S. Smerat, I. P. McCulloch, H. Schoeller +1
We study the spectral properties of the one-dimensional Kondo lattice model as function of the exchange coupling, the band filling, and the quasimomentum in the ferromagnetic and p…
Spin-polarized currents through interacting quantum wires with nonmagnetic leads
J. E. Birkholz, V. Meden
We study the performance of a quantum wire spin filter that is based on the Rashba spin-orbit interaction in the presence of the electron-electron interaction. The finite length wi…
Supercurrent and multiple singlet-doublet phase transitions of a quantum dot Josephson junction inside an Aharonov-Bohm ring
C. Karrasch, V. Meden
We study a quantum dot Josephson junction inside an Aharonov-Bohm environment. The geometry is modeled by an Anderson impurity coupled to two directly-linked BCS leads. We illustra…
Quenches in quantum many-body systems: One-dimensional Bose-Hubbard model reexamined
Guillaume Roux
When a quantum many-body system undergoes a quench, the time-averaged density-matrix governs the time-averaged expectation value of any observable. It is therefore the key obje…

Andrej Gendiar, Roman Krcmar, Tomotoshi Nishino
System-size dependence of the ground-state energy E^N is investigated for N-site one-dimensional (1D) quantum systems with open boundary condition, where the interaction strength d…
Dynamical simulations of charged soliton transport in conjugated polymers with the inclusion of electron-electron interactions
Haibo Ma, Ulrich Schollwoeck
We present numerical studies of the transport dynamics of a charged soliton in conjugated polymers under the influence of an external time-dependent electric field. All relevant el…
Pair correlations of a spin-imbalanced Fermi gas on two-leg ladders
A. E. Feiguin, F. Heidrich-Meisner
We study the pair correlations of a spin-imbalanced two-leg ladder with attractive interactions, using the density matrix renormalization group method (DMRG). We identify regions i…

Consequences of explicit symmetry breaking in a physically motivated model of SU(N) antiferromagnet in spatial dimensions one and two are studied. It is shown that the case N=3, wh…
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,…

We investigate the possible formation of a molecular condensate, which might be, for instance, the analogue of the alpha condensate of nuclear physics, in the context of multicompo…
