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…
