Spreading of correlations and entanglement after a quench in the one-dimensional Bose-Hubbard model
Andreas Laeuchli, Corinna Kollath
We investigate the spreading of information in a one-dimensional Bose-Hubbard system after a sudden parameter change. In particular, we study the time-evolution of correlations and…
Dipolar bosons in a planar array of one-dimensional tubes
C. Kollath, Julia S. Meyer, T. Giamarchi
We investigate bosonic atoms or molecules interacting via dipolar interactions in a planar array of one-dimensional tubes. We consider the situation in which the dipoles are orient…
Spin-charge separation in two-component Bose-gases
A. Kleine, C. Kollath, I. McCulloch +2
We show that one of the key characteristics of interacting one-dimensional electronic quantum systems, the separation of spin and charge, can be observed in a two-component system…
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…
