Sudden expansion of Mott insulators in one dimension
L. Vidmar, S. Langer, I. P. McCulloch +3
We investigate the expansion of bosons and fermions in a homogeneous lattice after a sudden removal of the trapping potential using exact numerical methods. As a main result, we sh…
The Drude weight of the spin-1/2 XXZ chain: density matrix renormalization group versus exact diagonalization
C. Karrasch, J. Hauschild, S. Langer +1
We revisit the problem of the spin Drude weight D of the integrable spin-1/2 XXZ chain using two complementrary approaches, exact diagonalization (ED) and the time-dependent densit…
Expansion dynamics of interacting bosons in homogeneous lattices in one and two dimensions
Jens Philipp Ronzheimer, Michael Schreiber, Simon Braun +6
We experimentally and numerically investigate the expansion of initially localized ultracold bosons in homogeneous one- and two-dimensional optical lattices. We find that both dime…
