Collective excitations in one-dimensional ultracold Fermi gases: a comparative study
Wei Li, Gao Xianlong, Corinna Kollath +1
Time-dependent density-functional theory (TDDFT) is a powerful tool to study the non-equilibrium dynamics of inhomogeneous interacting many-body systems. Here we show that the simp…
The quasi-periodic Bose-Hubbard model and localization in one-dimensional cold atomic gases
G. Roux, T. Barthel, I. P. McCulloch +3
We compute the phase diagram of the one-dimensional Bose-Hubbard model with a quasi-periodic potential by means of the density-matrix renormalization group technique. This model de…
Scanning tunnelling microscopy for ultracold atoms
Corinna Kollath, Michael Köhl, Thierry Giamarchi
We propose a novel experimental probe for cold atomic gases analogous to the scanning tunnelling microscope (STM) in condensed matter. This probe uses the coherent coupling of a si…
Spatial correlations of trapped 1d bosons in an optical lattice
C. Kollath, U. Schollwöck, J. von Delft +1
We investigate a quasi-one dimensional system of trapped cold bosonic atoms in an optical lattice by using the density matrix renormalization group to study the Bose-Hubbard model…
