Renormalization-group analysis of the one-dimensional extended Hubbard model with a single impurity
S. Andergassen, T. Enss, V. Meden +3
We analyze the one-dimensional extended Hubbard model with a single static impurity by using a computational technique based on the functional renormalization group. This extends p…
d-wave resonating valence bond states of fermionic atoms in optical lattices
Simon Trebst, Ulrich Schollwoeck, Matthias Troyer +1
We study controlled generation and measurement of superfluid d-wave resonating valence bond (RVB) states of fermionic atoms in 2D optical lattices. Starting from loading spatial an…
Spin-charge separation in cold Fermi-gases: a real time analysis
C. Kollath, U. Schollwoeck, W. Zwerger
Using the adaptive time-dependent density-matrix renormalization group method for the 1D Hubbard model, the splitting of local perturbations into separate wave packets carrying cha…
Orbital currents and charge density waves in a generalized Hubbard ladder
J. O. Fjaerestad, J. B. Marston, U. Schollwoeck
We study a generalized Hubbard model on the two-leg ladder at zero temperature, focusing on a parameter region with staggered flux (SF)/d-density wave (DDW) order. To guide our num…
Ground-state phases in antiferromagnetic spin-crossover chains
Carsten Timm, Ulrich Schollwöck
Spin-crossover molecules having a low-spin ground state and a low-lying excited high-spin state are promising components for molecular electronics. We theoretically examine one-dim…
Ageing phenomena without detailed balance: the contact process
Tilman Enss, Malte Henkel, Alan Picone +1
The long-time dynamics of the 1D contact process suddenly brought out of an uncorrelated initial state is studied through a light-cone transfer-matrix renormalisation group approac…
