Topological charge pumping in the interacting bosonic Rice-Mele model
A. L. C. Hayward, C. Schweizer, M. Lohse +2
We investigate topological charge pumping in a system of interacting bosons in the tight-binding limit, described by the Rice-Mele model. An appropriate topological invariant for t…
Large magnetic thermal conductivity induced by frustration in low-dimensional quantum magnets
Jan Stolpp, Shang-Shun Zhang, Fabian Heidrich-Meisner +1
We study the magnetic field-dependence of the thermal conductivity due to magnetic excitations in frustrated spin-1/2 Heisenberg chains. Near the saturation field, the system is de…
Non-Equilibrium Mass Transport in the 1D Fermi-Hubbard Model
S. Scherg, T. Kohlert, J. Herbrych +6
We experimentally and numerically investigate the sudden expansion of fermions in a homogeneous one-dimensional optical lattice. For initial states with an appreciable amount of do…
