Spectroscopy of ultracold atoms by periodic lattice modulations
C. Kollath, A. Iucci, T. Giamarchi +2
We present a non-perturbative analysis of a new experimental technique for probing ultracold bosons in an optical lattice by periodic lattice depth modulations. This is done using…

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…

One-dimensional density waves of ultracold bosons in an optical lattice
C. Kollath, U. Schollwöck, J. von Delft +1
We investigate the propagation of density-wave packets in a Bose-Hubbard model using the adaptive time-dependent density-matrix renormalization group method. We discuss the decay o…
